"Android System," "Android OS" and "Google Services" all killing my battery on SG3

[tuffluck]

Guys, 51 minutes of screen time is way way way too little for the Samsung extended battery to be at 50% battery on after a few hours. I also already mentioned screen is on AUTO. Here is better battery stats... So not helpful unless wikipedia just randomly runs in the background, and is using so much battery.

You don't want prcesses. Post kernel wakelocks and partial wakelocks


If you're rooted post alarms too

I don't know about the Galaxy S3 but my Merit with screen on you could watch the battery icon deplete. It was so bad it actually animated! Nexus 7 also sucks away battery with screen on, marginally improved at the dimmest setting. Reading ten pages of Moby Dick and backing out to home it was already down to 75%. Galaxy Precedent seems best of them with a marginal drain with screen on regardless of brightness. But it's such a tiny little thing that may have something to do with it. So far only Play Music eats it alive.

Only time brightness made a difference was my Tab 2 10.1. It gets three hours more out of a charge if the screen is at the dimmest setting, which basically disables the backlight as its that hard to see.

Thanks man! Now if you can help me read these darn things...

Just looking at the screenshots you posted...

You lost 31% over 8.5 hours. That's nothing to complain about.


But I'd charge it all the way up, let it run down to 10-15% and then post those screenshots again so we get the whole discharge cycle

Ah whoops, that's because I restarted earlier in the day after the heavy drain and posted BBS after with boot only selected instead of charge. Today its running great, 91% after 4 hours on time and an hour of screen time. That's how it should be. But every few days it acts up. I'll post stats next time that happens.

I have had heavy usage on my android os , something kept it from sleeping and I had an app that kept it from sleeping when screen off ,l have also adjusted the power saving settings and got from play store DS battery saver , you can schedule the phone to sleep at night so it saves battery and yes I have a galaxy s3 !!!

nothing is worse than when you pull out your phone from your pocket to find the screen on, and the battery at 25%

Today was one of those days. Even after a reboot I still burned through the battery. 10 hours on, exactly 1 hour screen time. Can you guys help me read these better battery stats?

After last update from Verizon on my S4 i've been having the same problem. This pics are from today after 3 hours on battery. The only thing i've done is play music and it's only 9%.

I feel like it's just android. I love using android but I don't think its very well optimized for battery life at all. It's hard to get the system in perfect balance so that everything runs smoothly and you don't have crazy processes running rampant in the background. And this sort of thing seems to have been getting worse and worse every time Google updates their services. They add more things, and do a lot more for us, but they don't optimize them properly.

Agreed. Google should aim at bringing optimisation to the forefront... get it forefront
And bring all those developers to their knees who use unnecessary privileges, insisting on unnecessary auto-starts and excessive CPU/RAM usage. At least develop something that can weed the woeful out and tag them on the playstore... wait... I'm dreaming again :slap:

Edit: still dreaming... how about a some rating based on CPU and RAM usage?

Google purchased a French optimization company, so its something theyll be addressing
