A couple of coworkers complained about their lack of battery life with their Androids.
One had a Galaxy S2 that he always has to plug in.
Another has, I think an HTC, and purchased a number of spare batteries and saddle back battery packs so he can swap around all day and put in chargers.

I have a plain 4, and can go 2 days to normal usage (3G is off all the time).

I mentioned to them about turning off 3G, but neither did not know if they could turn off 3G on Android.

Of course the 4S is more power intensive, but how bad compared to others?

Battery life on Android varies, really. Some people have good battery life, some have bad.

I can get 2 days out of my G2 pretty easily, and I've never really thought about turning off the 3G mode. lol funny thought there!

The battery life depends on a lot of things: LTE & WiMax modems eat up battery, large screens eat up battery, and HTC Sense is horrible about eating up battery. That, and while I can get 2 days out of my phone I usually get 1 - if I leave GPS navigation open and play internet radio at the same time I'd probably only get 4-5 hours xD GPS is particularly nasty on my battery!

Battery size, cpu power optimization, screen size, apps and widgets utilizing the cpu/gpu, modem type and use, and so on, all factor in to battery life. Some phones purposely come with cheap batteries (usually the cheap Android BOGO phones) and won't last but a few hours. Apple tries its best to optimize battery life, as I'm sure Samesung, LG, HTC and the rest do for their top of the line phones. These days I don't envy the engineers and coders that have to squeeze every drop of juice out of their OS, UI and battery for a specific phone.

The longest I've gone on my Galaxy S Captivate is 6 days without (fully) charging the phone. I never charged it past 60% because I kept forgetting to at night.

I have an SGS2 Skyrocket and leave LTE and WiFi on all the time.
I can get through an entire day of my normal use and still have approx. 20% battery left when I go to sleep.

The newer LTE radios and SOC setups are not as power hungry as the earlier versions.
Plus the power management software has improved greatly.
The phone will idle the CPU at 385Mhz or deep sleep mode between screen usage.

When I had my SGS2 I would get 1 day stand by battery and 5 hours usage. (Wifi browsing some texting no music). With 4S I get 7-8 hours usage and 1 day stand by with the same usage as my SGS2.

Which SGS2?
There are 5 versions just in the US.
Hell, AT&T carries 3 of them. The SGS2, Skyrocket and Captivate.
Each uses a different SOC, so their power usage will vary.

The Skyrocket (SGH-I727) and the T-Mobile version (SGH-T989) are the same phone. They both use the same pentaband radio (MSM8260). You can flash the T-Mobile radio onto an AT&T Skyrocket and is will work on T-Mobile's AWS 3G band.
Just like you can flash the Skyrocket's radio onto the T989 and it will active the LTE frequencies on the MSM8260.

As you can see in my location, I'm not in the US. So I couldn't care less what version it is.

I suppose it's the "international version". Anyway, I've had it before the SGS2 was even announced for US.

Turning off 3G is really not a feasible idea. U buy such a hi tech gadget only to not utilise it at its fullest..

Even keeping 3G on will get u a day of usage.. That's not bad as long as it gets u day..

Without any special settings, just daily use with everything on, etc - I unplug at around 6 AM, and plug it in at around 9 PM (So 15 hours) with about 20% left. That's using the phone, playing games, using 3G etc.


On a Samsung Galaxy S2 i-777 (AT&T)


With Power-Saving Mode ( Wi-Fi off, GPS off, brightness low, Data Network Mode off, etc), I can easily EASILY go >4 days.

Wow... jerk city around here.
My point was, there are many SGS2 variants out there.
Some suck batteries dry and.some don't.

There is no single "international version"
The Captivate is the original Galaxy S (SGS1) variant from 2010.

The new Captivate is an SGS2 phone. ;)
I believe it's official name is the Captivate Glide.

In my experience I have to charge my 4s every day, during the night.

For comparison, my Lumia 800 (it's not and Android, but a WP7) with the same kind of usage lasts until 18:00pm ... while my old iPhone 4 was slightly better (one day and half).

There are a lot of variables here...

Carrier - If you are in a weak signal area all bets are off on battery life.

CDMA or GSM - GSM seems to be a tad less battery hungry

And the one that makes the biggest difference USAGE.

What I consider "Light Usage" might be "Heavy Usage" to anyone else.


But if you wanna deal in generalities

Android sucks because this is a Apple forum. :D

I have an iphone 4 and lose about 40% battery overnight doing nothing. 3G is on, wifi is off, bluetooth is off, and email checking is off. I hardly get half a day with my iphone before it dies and I only use it for about 10 minutes checking email or websites before it dies. However, I can talk 4-5 hours on the phone over 3G before it dies.

With Android a lot depends on how it's setup, lot of people have updates up the wazoo and stuff running in the background or checking 24/7 etc. Plus cell reception can cause bad drain depending on location and carrier. And then some have different versions, like my GS2 is only 4.3" and has the efficient Exyno's cpu. I haven't rooted or rom'd mine yet but going too, battery life is even more awesome with a custom Rom and no bloatware.

All our phones are on at&t with excellent reception in South FL and for battery life with our use I would rank them as:
4 > i777 GS2 > 3GS and 4S about a tie. My primary is the i777 and gf's is the 4S for work.

This seems like a real hit and miss problem (like the iPhone 4s). Check out this thread...

http://forums.androidcentral.com/verizon-galaxy-nexus/156257-whats-your-best-battery-life.html

Then you can easily find someone complaining about how terrible theirs is. It looks like the latest version of ics may help. I'd like to get a gnex just to see if I could figure out the problem, I'm a geek like that.

Btw there are more threads about android devices on macrumors then there are on androidcentral lol

Here is what I have found. iPhone 4 seems to have roughly the the same to slight better battery life for the same usage. If the screen is on a lot and cell data is being used heavily it will drain the battery in around the same time span. A friend of mine has a 4S and I have an Atrix 4G (both on AT&T). Often time he is limiting along at the end of his battery life in the evening but he is on the phone all the time. Our batteries seem to drain at around the same pace. It is the screen and cell data that toast these batteries. Comparing two people usage is not exactly fair as people have very diferent usage patterns.

I will say the battery life on my phone jumped a lot once I got a tablet as my phone spent more time idle. It went from 12 hours to well over 30 hours but that was due to greatly reduce time of not using the screen.

If battery is your main concern get a Droid RAZR MAXX. That thing has a crazy big battery in it.

You'd also be surprised with the size of extended batteries you can get with a lot of phones that have replacable batteries too. I think mugen makes a 3900 mah battery for the nexus s. Lol

Oh I know that I am just surprised that they can put such a big battery in and still have a nice form factor. I like my RAZR, but am jealous of that huge battery in the MAXX.

I have the MAXX. It'll easily last two days with everything enabled (including LTE) and still have 20-30% battery remaining. The only Smart Action I have running is Night Battery Saver, which shuts down background data, WiFi, GPS, and cell data while I'm asleep. The MAXX is a fantastic device - Motorola got this one right!

Of course you can turn off 3G on android phones. It's a pretty strange thing to complain and not know.

With 3G on all the time (what's the point of a smart phone if you only want to use slow data?) the iphone 4 lasted about the same as my Galaxy Nexus. People seems to think the Gnex has bad battery life. It really depends on what your settings are. If you leave tons of apps running in the back ground chances are your battery's going to take a beating because it's real multi-tasking on android. Double-twist for example has a DLNA server mode which it tells you if you turn on it will impact your battery. The other thing which I found drained the battery like no tomorrow was the vibrate on type setting for the keyboard. As a motor draws the most current when it starts up you can imagine if you keep starting and stopping the vibrate motor it's going to beat up your battery as well.

Anyhow the issue isn't that bad. It will last you a day no problem.

According to anandtech, the 4S can browse for 9+ hours on 3G.

This matches the Razr Maxx. It's pretty impressive, considering the iPhone has less than half the battery capacity compared to the Maxx.

I had the Maxx for 14 days, but switched to the 4S. The 4S with a battery case gives me plenty of juice to get through the day! :D

I have a GSM Galaxy nexus and looking at the settings right now it shows 69% left and been running 9h 8min on battery. I have an iphone4 as well and I'd say, depending on what you do, the Nexus matches or exceeds the iphone4. I certainly don't have to plug into a charger during the day and usually end up at 11pm with over 40% left.

Most of time non-3G suffices. Rarely I turn on 3G for browsing.

I have 200MB / Mo plan, and use this to reduce the chance I run over, and so far am about 100MB/Mo usage.

The iPhone with it's regular battery should get through the day. Mine does, even with heavy use.

The ultimate is probably RAZR MAXX for sheer battery life, but I'd say the iPhone is far and away better than most Android phones. I had a Captivate, and that thing wouldn't last the day. The iPhone is usually at ~50% at the end of the day, on a really, really heavy day, it will be around ~20%.

The reason many people think some of the new androids outshine the iPhone 4/4S in battery longevity is their usage patterns. If your total screen on time is lower than 3-4 hours than android will always win because not only they can run for 3-4 hours max constantly (in my experience trying quite a few over a few weeks and months), they will have far better standby because 1600+ mah > 1450 mah. It is simple math. Screen off means both phones tend to draw almost equal juice if configured properly in an identical manner and the android with its huge battery will always win.

But, this all changes once your usage pattern goes further than a couple hours of screen time. I used to read quite a bit on my phones and with the long commute came youtube and video consumption and the iPhone 4 always ended up with 5-7 hours of solid screen on time while the android would struggle to touch 4 hours. That is where iPhone shines. Its ability to constantly sip juice while doing the exact same thing compared to the gas guzzler android.

Part of the reason is ofcourse those huge screens too. So in the end it really depends on usage and preference. Glad motorola has finally addressed this though and my friend with the MAXX is all praises about it. So i am keen on the newer phones coming this year. I guess this is the year android OEMs will finally cater to the battery crowd.

I can't speak for ICS since I haven't seen a test but iOS does a better job then Gingerbread using less power while web browsing. If you compare talk time Android usually comes up on top. This is probably cause talking uses similar amounts of power and the phone with the largest battery wins.

I can't get through an entire day with my 4s and I only use it for voice during the work day. I'm always near a charger so its not an issue.

The Skyrocket (SGH-I727) and the T-Mobile version (SGH-T989) are the same phone. They both use the same pentaband radio (MSM8260). You can flash the T-Mobile radio onto an AT&T Skyrocket and is will work on T-Mobile's AWS 3G band.

It's very relevant.
If you want to compare battery life, pick a device.
The SGS2 line alone uses several CPU/GPU SOC configurations.
Some are better than others at managing power.
The SGH-I727 vs. the SGH-T989 is one example of how the exact same device can also have variations is power usage.
The T-Mobile version gets better life due to the fact the the LTE radio is disabled since T-Mobile doesn't use it.

If you failed to see that, you need help.

I hope that IF Motorola does make this year's Nexus phone, they better pack a battery at equal or even higher capacity than the MAXX.

It looks to me the MAXX wins battery life in terms of voice calling, LTE, and even Wi-Fi at 12+ hrs! Seeing 20+ hours for voice calling is just plain ridiculous for a smartphone. I hear PhoneDog ranks the Galaxy Note as probably 2nd best when it comes to battery among Androids at least based on real life usage.

Battery life for Wi-Fi browsing is the most important to me since I am usually on it and iPhone 4 was the best in that area back in 2010 and most of 2011. Looks like the MAXX takes the crown. I can't wait when smartphones have Wi-Fi browsing and video playback at 20+ hours and music playback at 100+ hours in a single charge. I would probably only need to charge it ONCE per week and can have the Wi-Fi switch and push notifications always on. Perhaps even 2-3 weeks since I have multiple phones to use.
