Continuing the tradition from previous betas....

Post your battery in iOS 7.1 beta 4 that you notice compared to beta 1/2/3 and/or iOS 7.0.4.

Can an mod change the thread title? There is a typo there, my apologies.

Don't stress about battery life

I don't get these battery life threads. I mean, you can't be precise enough to tell if there's a difference unless you manage to repeat everything exactly, no wifi or cellular, restore your device as new, otherwise there are like hundreds of factors that can, and I am pretty sure it will, change something. Your signal is weaker - battery is used more, you use cellular data a bit more - battery is used more as well, you get more notifications etc. You may encounter a bug which would make you think that the battery life is much worse.

Even if there are some tweaks that Apple may have made, you won't notice them, because it can't be some drastic changes. Why? iOS is already pretty great with managing battery.

I respect your option :), But Apple can make changes in the software that can be pretty noticeable, look at OS X 10.8 VS 10.9 in terms of battery life.

Yes of course, but it's a major release. I am sure they'll do something about extending battery life in iOS 8, but those x.1 releases are like service packs, many improvements and bug fixes and some of those bug fixes may happen to be battery eaters :)

I do hope that a final 7.1 is going to improve battery life and without a doubt overall experience.

About the Same, Maybe a Bit Worse

I'm getting about the same battery life on Wi-Fi. I spend most of my day on Wi-Fi but for about 7 hours a day I'm not on Wi-Fi. For that time spent on 4G/LTE I'm seeing slightly worse battery. I'd estimate it at about a loss of 10% total.

If only apple had somehow managed to "tune" another few hours from the battery lol. Sadly, it's much as beta 3 was for me... Which was much better than beta 1 and 7.0.4 (never used beta 2).

I'm getting okay battery life today, I installed b4 yesterday and drained it to 0%. Today I've been unplugged for 16 hours and have 3hrs 40 min of usage and am at 57%. I've been on LTE all day, this is still slightly worse for me than 7.0.4 was on my 5s.

I haven't even been able to do a full charge cycle because my phone shuts down at 12%

Here's my first full cycle on my 5s running beta 4. It's about 90% as good as 7.0.4 was for me.
LTE 80%
3G 15%
Wifi 5%

A charge cycle is using 100% of the battery and it doesn't have to happen all at once, e.g., use 50% of the battery, charge, then use another 50%. Or using 10% a day for 10 days, etc. Apple's recommendation is at least one charge cycle per month.

That's horrible? It might not be great, or even good, and perhaps even below OK, but it's still a step or two above horrible I would say (and that's basically judging on just a little less than 1/3 of the battery used, as it can be different by the time the whole thing is used, given that battery usage isn't linear).

Right here
7.0.4 battery has been better than 7.1 B4 on my 5s. 7.0.4 actually is a lot better for me but the crashing thing is fixed in 7.1 B4. So far. I think that we see 6 or 7 betas out of 7.1 before it's released and a 7.0.5 very very soon.

My contribution to this thread isn't based on statistical data, but I must say that with each beta my battery life has gotten much better on both my iPad and 5s. Just from real world usage from the extent of 7.0.4 up to beta 4, my battery lasts all day and if I forget to charge it at night...no big problem. I still have 20-25% remaining in the morning.

I'm in no way a power user, but my typical daily iPhone activity rounds out to receiving about 100-150 emails a day, reply to maybe 20% of them, check FB and Twitter occasionally, 15-20 calls a day, 20-30 texts a day, browse internet during lunch and breaks. Pre-beta I was always in the red when my work day was over with when I started my 40 minute commute home. Beta 4 I'm sitting anywhere at 35-45% with the same activity before my commute. On a side note, I run all features enabled like location services, Bluetooth, etc. I'm one of those users who believe that if they have features embedded in the software, why not take advantage of them. I've always dealt with inefficient battery issues by always having chargers located from my home to my office and in between. Now it appears I can bring my chargers home. :)

iPad battery life is in a league of own on beta 4!!!

A charge cycle is using 100% of the battery and it doesn't have to happen all at once, e.g., use 50% of the battery, charge, then use another 50%. Or using 10% a day for 10 days, etc. Apple's recommendation is at least one charge cycle per month.
While you are correct on all that, a full charge (the recommendation from Apple) used to be posted as a drain to 20% then charge back up to 100% at least once a month. That wording has since changed on their battery info page to match what you are stating. Also the Li-ion batteries are not required to discharge before charging, in fact they prefer not to be drained to low. I am wondering if Apple finally realized this and changed their information? Their page was always contradicting the battery industry about Li-Ions. Interesting

However for the Apple battery meter, a calibration of a full run down til it shuts off then a full undisturbed charge to 100% is typically what get it back in sync and reporting correctly. As for 7.1 b4 on a 4S, battery is better than its ever been even when it was new. (2+ yrs old now)

----------

On what device because that isn't "that" great IMO...
I am betting a 4s. That's is typically what I would get on mine. Of course depending on a lot. like music would be way more but typical day usage that is good battery on a 4s.

If its something other then well....

I don't want to seem argumentative on this when I say that the verbiage was "Be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down)."

Here's the link from the Internet Archive Wayback Machine from June 14, 2013.

Ha ok, Yes I do remember that but have since heard the 20% deal. I have always followed the original instructions once a month as I just figured Apple had a reason (like the calibration) more so than to "exercise" the battery. And yeah WAY BACK in June 2013 lol

lol - yes, I was still running mine down completely, making sure my Mom did, telling folks to do it until just a few months ago.

Beta 3 had AMAZING battery life; Beta 4 is horrible. I sincerely hope they go back to the beta 3 battery algorithm as beta 4 is sucking my battery dry.

I can almost guarantee its basically identical. Do a clean DFU restore and it'll be back to normal.
