Help I get terrible battery life

[zemerick]

Don't forget the cell standby reporting values are incorrect (see signature for details) so that could be a red Herring

Well, that did lead to several interesting threads. ( After I found your signature..had to go up and look at your first post in this thread. All others are just blank white spaces. )

Anyways, from the sounds of it, having multiple accounts syncing seems to be a very big issue. I wonder if they are not syncing together IE: If you have 2 apps syncing every 5 mins, but they are doing it at say 2:10 and 2:12, effectively having your phone syncing every 2.5 mins. Add in a 3rd and it gets worse, etc. until you have your phones data always on as something is always syncing. This would indeed obliterate batteries.

Try setting Network Mode to GSM only when you're not mobile browsing. It's under Settings > More Settings > Mobile networks.

I know 4 different people with this phone (including myself) and all of us complain about the battery life.

Im charging mine twice a day with normal usage.

Could you post a screenshot of your battery results?

When Media Server is one of the top in terms of battery usage, what does this usually mean?

Saw this reply from another thread.

Media server is the audio processor for the phone. If you're watching movies or listening to music, the usage of this will go up.

Here's what I'm getting...I feel like something's wrong. This is my first full charge.

When I bought the phone new, the battery was at about 40%. I drained it completely before charging it. Will it have permanently reduced battery life because of this?


Screen time: 4h 4m 49s
This is my first full charge.

You guys have to remember, the first 3-4 days of owning a phone you should get really bad battery life. Youre going to be using it A LOT, even if you dont realize it. When youre screen is using up almost 60% battery, trying turning the brightness down. But most of all, give it a couple days.

What do you classify normal usage? Can you provide a screen shot?

I haven't been using a huge amount over the last week or so, but there is a screen shot of my battery.

No, that would not have hurt the battery.

Also, why do you feel something is wrong? I see over 17 hours of use. The first half is light use, on track for something like 3-4 days of charge. Then, there's a substantial amount of screen on and network usage for the second half, and still 14% of the battery left. The battery was also never full, it says it started at 90%. This is a usage of 76% over approx. 17.5 hours. At this average rate, you had over 3 hours left. At the heightened rate though, you went from about 78% down to the 14%, for a usage of 64% in approx. 9 hours. This means you still had just shy of 2 hours left of moderate to heavy usage.

You don't seem to have anything major wrong, but I wouldn't be surprised if there are some small things you can do. Things like checking screen brightness, changing how many things auto-sync, the frequency of the auto-syncs, etc.

I can't really give anything more specific than this as I'm still waiting for my phone, so I don't have exact settings or where to find them just yet.

I normally get all day out of mine, when I am at work and I work 12's I listen to the radio a lot and also browse the internet, there i get about 8 hours, but I keep a charger at my desk.

If you are getting horrible battery life you may be going in and out of 4G or if you dont get very good signal in the home.

OK, battery was at 100% at midnight, I turned off wifi, bluetooth, GPS, mobile data, and sync, and turned on airplane mode. I did not turn on power saving. Woke up at 6 AM and battery was at 90%. That's 60 hours which would be great if it wasn't in Airplane mode. I don't expect to get 60 hours out of it while using it but If I could get to 12 I'd be happy.

 

[barryl85]

What the hell is GPSD and why is it taking up 44% of my battery use?

Incase its linked - I do not have GPS on.

 

[gabquintero09]

What? 17hrs :O

I get 12 hours, should I be concerned with low battery life haha

Same thing just happened to me. Went to sleep with 100% and woke up with 90%. I checked the battery log and it says that Android OS was in "stay awake" mode for 2 hours. Does anyone know why this could have happened?

Greetings kanezfan,

I would ask what your reception is like? Not going by your bars, but actual dbm's. If your phone is constantly searching for signal, that will kill a battery quickly.

You can find your dbm's under setting>about phone>status, under signal strength.

70-90=great

90-100=so so

100+ = not so good

I must say I am actually very pleased with battery performance. This far outlasts my Atrix2 or Inspire. Easily on par with my iPhone 4S battery life.

 

[arche3]

About half the time on WiFi. Other half 4g.

 

[dennygreen]

Is there a setting somewhere like on my droid x where you can have the data shut off after a certain amount of time, such as 15 minutes?

 

[vipercwf]

I'm definitely having this issue. My phone was charged to 90% last night when I went to bed. When I woke up, it was completely dead. I was only asleep for 7 hours, no idea when it died either.. Syncs are off (besides gmail) tried all the basic things. Bout to go to bed and unfortunately my battery is about dead. I'd like to do a screenshot overnight in idle condition when on a full battery because it completely drained just sitting there.

I actually called AT&T about this yesterday to ask this very question. While I was on the phone, my dbm was hovering between 89-95 and I can't remember the asu number next to it. This was outside with almost a full signal indicator. Right now at home, it's 98-102 dbm with 42 asu.

The AT&T rep told me I live between 4 towers in south florida.

In the time it took me to write this reply, my battery went from 99 to 97%.

I had terrible battery life at first until I realised that S-Voice is set by default to automatically listen to you all the time for voice commands which drains the battery really quickly.
Go into S-Voice and turn it off in the settings. I did and noticed a mahooosive improvement

 

[nnikolic88]

Wanted to update this, my phone is finally working correctly. After reading numerous threads here and elsewhere, I installed CPU Spy and also shut off my phone and removed the battery. After I did this, all of a sudden my battery started lasting 12 hours with very heavy use, bluetooth, gps, wifi, and 4g all turned on at all times. I kept the phone in low power mode because I didn't notice any slow downs whatsoever.

I drive around all day long for my job repairing computers all over town. Typically I'm in 6-7 offices for anywhere from 5 minutes to 2 hours (though rarely that long). Many times I'm driving an hour or more to get to where I'm going and I have music playing with bluetooth to my car radio, and I constantly check the maps, and make and receive phone calls so 12 hours like this makes me very happy.

This past weekend, my battery lasted 18 hours without a charge with normal use, basically phone calls, texts, checking facebook and twitter a few times, playing music, so I'm very, very happy. I don't know which of the two things I did fixed my battery issue but I was starting to think there was a hardware issue since I would lose 40% battery life in like 3 hours of use.
