No background fetch and cpu throttled down, that's what I noticed so far.
I guess you'll have to check email manually but this is not a big hassle if you don't receive too many emails during the day.
I'm thinking of doing the same with my mother-in-law, she'll get plenty of battery life and barely notice the decrease in speed.
 
Another related question. For people that already have things shut off that apparently the low power mode shuts off - would we see any increase in battery life if we turn low power on?
I already have mail fetch off, background app refresh off, auto downloads off, and visual effects off. I've always had those things off and still have to charge my battery twice a day.
Should I expect to see any improvement?

You must be using your phone a lot to have to charge it twice a day. I consider myself a pretty heavy business user and still have 40-50% remaining at the end of the day. Are you gaming all day or watching movies?

What phone do you have? Apple has a program to replace the battery on some phones. And what do you do with your phone all day that eats the battery?

One person's "heavy usage" is someone else's "light usage". I don't consider myself a heavy user at all, but I was very lucky to have 20% left after a 12 hour day, for which 8 hours I can't use a cell phone.

If I recall low power mode also downclocks the processor, so you should see another slight improvement there. Always worth giving a shot!

iPhone 6. I've had every version since the 4. Same story. I get 4-5 hours usage max. I've tried everything under the sun. Apple has tested battery. Etc. there's no solving this for me. I've accepted the fact that iphone batteries aren't great (save for the 6+ but that's too big for me).
Anyhow, I don't want to derail the topic. Anyone know if the low power mode does anything else aside from what's explicitly listed? Or is it pretty much no brainer battery saving stuff that most of us with battery problems do anyways?
 
He could also be in a low signal area with a 6, whereas you always state you use a 6+. Those two factors alone would help contribute to his less than stellar battery performance.

Agreed. Instead of low power mode, likely best to just turn your phone off for those eight hours of non-use. If the signal is low, even 8 hours of non-use will run a battery down. If that unused phone is inside a metal locker it will really hurt the reception.
 
Enabling Low Power Mode:
  • Decreases your iPhone’s CPU speed
  • Stops fetching new mail messages
  • Stops refreshing apps in the background
  • Disables motion effects and animated wallpapers.
Additional power-saving measures that it does NOT affect (which can be utilized) are adjusting screen brightness and toggling various antennae (wifi, bluetooth, etc.)

The phone was in my pocket for the eight hours, not moving more than 10-20 feet in a perfect signal area. Turning WiFi off helped a bit, since I wasn't using it for data. It was connected to my Microsoft Band for notifications and alerts.

I'm not complaining about my battery life, or making fun of a product. I am simply stating that someone's "heavy usage" could be someone's "light usage".

You're not complaining, but you should be. If all of the above is true, you could probably get your phone swapped. You either have some processes tearing through your battery or you have a defective battery.
 
I'm staying in that mode forever, I'm not a major user and speeds feel unchanged yet 24 hours later with 6 hours of usage I'm at 45%

Happiest day of my life lol. 5s 32gn

Nah, it's fine. I spend around 30-40 minutes during break watching Twitch or some streaming video. When I get off work, I usually play a bit of games waiting for traffic to die. I get around the same battery life no matter which phone I use, so I am used to it. I usually have 3-5 email accounts set to push if they can. I have like 4-5 social media accounts synced, and a bunch of background notifications like eBay, Simple, The Score, etc.

they shouldhave something called blackberry mode for the messages, email and callers only. since those were the only things that worked well for blackberry.

If you are in a location where cellular signal is weak, it can run your battery down very fast, because the cellular radio is working very hard to lock onto a signal. Whenever I am in Hard Rock Casino in Tampa, the Poker Room has a very weak ATT signal and my battery goes down fast. I have to keep it on Airplane mode. That might be happening to you.

Nope, as outlined in a later post, I am in a perfect area for reception. The building I work in has an AT&T tower on top of it, or a booster...not sure which. Either way, I get a really good signal. It just has to do with the amount of background services going on in the background and what I do with it after I get off work.

We can more or less out this argument to bed now with the new battery meter. It tells you what apps are using what with screen on time versus in the background.

I've used low power mode quite a bit and not really noticed too much difference in performance, unless you're going to be using power hungry apps that is, then the downpowered CPU might affect it a bit.

The only thing is (unless there's a setting I've missed), you can't have low power mode always on. When you connect the phone and it charges to 80% you'll get a message saying it's sufficiently charged and low power mode has been turned off.

Confirmed. I just brought battery down to 77%, manually turned on Low Power Mode. Charged up to 81%, and it was turned off automatically. There doesn't seem to be a way to keep it on permanently, even when manually turned on.

I did not even notice that! Thank you so very much for pointing it out. Now I can easily compare my battery life between devices (especially my old Android phones), and see how much I'm online at work... Shhhhhhh
