Battery draining faster over time?

Hello to all my fellow S3-users.

Has anyone experienced a fall in the usage time they get from their battery over time? I'm pretty sure that my battery is being drained faster and faster every week. I've had the phone just over 4 weeks now and I'm sure the battery was a lot better before.

For example, see my attached screenshot for today's battery use.

I stuck it on charge for 10 minutes, and I've not really used Wifi or the mobile data today, I get a rather large number of texts/emails/WhatsApp messages daily and I don't play games on the phone - and my battery has hit less than 20% today. On another day, a similar days phone usage, I end up with around 50% at the end of the night.

I am an adept S3 user so I'm not looking for advice, just comments as to whether others have also noticed/experienced this.

Many thanks.
 
Thats funny you post that.....me and my wife both are saying the same thing. We are on the Verizon network and were thinking it was something with them.

It's really odd, two days last week both of our batteries were going completely dead in a matter of 5-6 hours, recharge, then dead again... repeatedly with normal/minimal use. Then on day 3 back to semi-normal battery drain.....still, seems worse now than when new.

I experience the same thing. I am on VZW as well.

From a full overnight charge at 7am my phone would get a good 16 hours of battery life. I remember it being at 20% before I plug it in at night around 10pm. Now... my phone is at 35% come lunch time (1pm) :(
It makes me very sad... like the battery life was just an introductory feature.

donas and uhohsteveo I can almost guarantee it is changes you have made. It could be an app installed that is keeping the phone awake, or something that uses the radios a lot, etc.

That is not normal behavior.

Minimal usage should net you 1-4 days ( 24+ hours, not just a full days charge. ) You shouldn't get down to 5 hours unless you are near 100% usage.

I've been having this problem too. There is something weird. I notice the Android OS process takes much more battery than even my screen or standby. It also randomly started to reset itself sometimes (not the phone but you can tell in the notification bar icons restart and phone is unresponsive for a minute) . I'm trying some reinstall of programs and hope to see some improvements.

Just throwing this out there as I don't know if it has any thing to do with what you have but battery temperature does make a difference. Most batteries are designed to work in the room temperature range. If you take your phone to the beach and leave it in the sun or you are working inside a freezer environment (Like in a grocery store) it will drain faster.

I work with batteries a lot for work and this is true of almost any battery (Don't put batteries in the freezer either).

Well the top juice suckers are:

Android System: 16.8%
Lookout Mobile: 10.2%
Exchange Services: 5.8%
Kernal: 5.1%


Should Android be that high?
and is there an alternative to Lookout?

Have you updated your phone recently? Mine started getting shorter battery life after the update...

For 3-1/2 weeks. I charged until it was at 100%, which only takes about 2 hours.
I did notice the battery having less juice over time.
Then, two nights ago I fell asleep with it charging and didn't remove it after 100%. but it charged for maybe 6 hours while I slept.
Since then it's back to normal amount of power when I plug it in.
I am once again back to what I was before the power draining.
I don't know if it's appurtenant or not.

its probably some apps u installed that keeps the phone awake more than previously. if you look at the battery chart, the awake time during screen off is quite high. ideally, it should be as low as possible to have more deep sleep time which saves battery.

to have a better idea of what is keeping your phone awake, try using betterbatterystats from the google play. some of the apps i have experience with that keeps the phone awake are touch and line. auto sync also keeps the phone awake alot if you are getting emails frequently.

@ OP...just this Tuesday I got 22 hours on a charge with fairly moderate usage! Best so far...then Thursday I got about 15 hours with the same usage. And yesterday my battery only made it to about 12 hours before needing a charge? This morning woke up and charged my phone to 100%, took it off the charger at about 10am, by noon I was down to 78% with hardly any usage? No apps running either. Who knows, did a battery pull, and its charging right now, see how it fares after this charge.
