Better battery on ICS.....

[SYMAWD]

My battery was terrible the first few days, but today it has been much better.

What uses most of my battery is the display.

I can't turn everything off, or why even have the phone? These phones are meant for multi tasking and heavy use..

Ditto about the display. I keep mine at the first setting on the stock widget, which I guess is 33 percent. I've adjusted to it and anything brighter seems too bright. I am thinking that using auto brightness may actually use more battery, since the phone is constantly monitoring conditions. That's my reasoning, anyways.

And yes, this device is so much more than a phone. In fact, I probably use voice the least. So I agree that it is a shame to have to turn things off. I mute the phone sounds while at work for 8 or 9 hours a day and only use bluetooth while in my car or exercising (that ain't often...) but let everything else pretty much run wild.

i have my brightness turned down to a quarter of the way and always leave wifi on i had the same settings on gb as well i noticed a little bit of droppage in battery usage and also when i go to bed, i put the phone in airplane mode as so my phone never really shuts off

Those are some pretty amazing numbers.

Lucky for you! Mine seems to be worse than ever from the update! I unplugged it when I got up from work, put the screen on once to check the time, placed one 2 min call to my husband and 1.5 hours later it was down to 75% already. If I'm actively using it, it drops one percent per minute. Ridiculous. Anybody else having any battery draining issues?

Yes! I get down to 50% just from watching a couple YouTube videos..

yep...battery life seems to be twice as good (or half as bad) now.

My battery has been draining pretty fast. I unplugged it at around 6:45-7am and it's barely lasting 'til lunch time. Also my extra charger can barely juice it up enough and takes forever to charge it when before it worked just fine.. Also tends to overheat a little easier.. I have an extra stock battery... I'm gonna try that one and see what happens but I doubt it'll be much different.
Also my display is using WAYY too much battery.. Over 90%!

Sounds like for some their phone is not going into deep sleep mode, thus causing increased battery drain overall, even when charging (thus causing the longer charging times). According to a thread over at XDA (ICS - Deep Sleep issue... Related to Charging? - xda-developers), the problem can occur with ICS when a USB charging source is connected to the phone that may then trigger a process that prevents the phone from going into a deep sleep. A few workarounds to ensure that process isn't preventing the phone from going into deep sleep:

- Reboot the phone after connecting or disconnecting a USB charging source
- Charge the phone with it powered off, disconnect USB cable, then turn on
- Use an external battery charger and swap out for a fresh battery (avoids the USB charging source)

My battery life is somewhat worse under ICS, but I think it might be me, playing with the phone more now that the update is finally here. It now barely makes it through the day, it used to have more left at the end of the day. I charge it overnight every day so I can't tell if charging is slower.

I have disabled some bloatware and will continue to do more over time. I am only disabling a few things at a time in case something I disable causes a problem.

The charging is slower than slow. With my display on and it charging, it took five hours to charge like 45 percent. I said to hell with that. I put in my spare charged battery and put the one from the phone in the charger. Geez, really ... five hours for 45 percent!? My battery never took that long to charge.

Love my phone ... don't love the battery! And I will give the Maxx credit for setting a new standard in battery life. Let's hope HTC catches on in the future!

That's not good. My battery charges rather fast, much faster than it did on gb. I wonder why that is happening.

this is not your mom's!

There is no Holy Grail for battery life on Android. With that said, some will see better battery, some are going to see worse. Everyone has different usages of their phones, and it's such a subjective thing. I'm still running the .10 leak, not the OTA, and the first few days my battery was HORRENDOUS. It as leveled out to back to GB life, but I never got better life (maybe leak vs. OTA but I doubt it). However my wife has different usage patterns than I and since the OTA, hers is getting much better battery life.

Take it with a grain of salt. Any Android update takes a few days to "settle in" and learn your habits and tweak/adjust itself accordingly. At the same time, it's always wise to check on your phones usage. Occasionally an app stays open, an app is sucking juice more than you thought, or surprise, you've been on it more than you thought today and the screen has just zapped all the power.

This makes sense, since I never had a battery charge as slow as it did yesterday.

As someone mentioned, it seems ICS is better at managing apps. When you close 'em they stay closed, whereas GB seemed to keep apps as "running" a lot of the time even when you closed them (or, at least, take longer to close them).

I think it must also have helped to disable the bloat and turn off a lot of features that always seemed to run. I find JuiceDefender (free) works well on ICS and I've been using Apex Launcher with only five home screens instead of seven, which means less battery-sucking widgets (not sure if that makes a difference).

I did the ICS OTA on a stock non-rooted GB Rezound and there was no improvement in battery life. Doing a factory reset after the upgrade and the battery is enormously better. The factory reset does the trick for getting better battery life.

Does anyone know if Bluetooth use gets lumped into screen use in the battery use menu. I would have thought it would be included by itself or with wifi but my screen use is at 72% after being at work for twelve hours (some use before and after as well). Note that extended battery is at 16% now. Says the screen was on for around one hour forty minutes. I used Bluetooth for listening to podcasts for about 10ish hours. I would think a fair amount of the power used would be for the Bluetooth.
