My Android phone, a Samsung Nexus S, operates on Jellybean 4.1.1. Since the latest update, I've noticed a dramatic decline in the battery life--it will go from fully charged to dead within 3 hours of intermittent use, regardless of whether I'm on a 3G or Wifi connection. How can I optimize the battery life on my phone without losing its functionality?
I bought the phone in January 2011, almost two years ago. It stays on all day if I put it into airplane mode. The battery usage tracker reports that the exchange services are using almost 60% of my battery life. I've done some research and it seems to be a common problem, though I'm not sure if it's due to the OS upgrade (all devices with Jellybean) or just my model's hardware, since Jellybean was designed to play with the newer Galaxy Nexus.
Things I've done:
-turned off Google Now
-restricted background data
-limited location services (I still need to use Maps)
-turned sync off for every Google service except Calendar, Contacts, Gmail and Reader
I don't want to turn off sync entirely, because that defeats the purpose of having a smartphone for me. Ignoring the other problems I'm having with the upgrade (Maps being finicky with the history function, Google search returning a page with unclickable results, slower response times), I'd like to be able to use my phone with some regularity without being slaved to a charger. The battery can get very hot and recharging takes hours, unless the phone is switched off during charging.
Has anyone else been experiencing similar problems? Is there a way to selectively sync (by location or time interval), or make exchange services stop being stupid and a battery hog? Are there any apps I can download to track my battery life better or diagnose the problem? I used to be able to turn my phone into a wifi hotspot and use it with my notebook...those days are long gone.
My phone's not rooted and I'd prefer not to do that, so simpler solutions are better.
Things I would consider doing but are not ideal:
-downgrading to Ice Cream Sandwich
-deleting and resetting Exchange Services
-performing a factory reset
-buying a backup battery to swap out (I'd rather solve this on the software side)
But I will if I have to, so any directions for those would be very helpful. I'm only a basic computer user, no programming knowledge, but I can find my way around instructions. This is a known issue that I've read up on (here
, and here
, for example), without any clear solutions. Unfortunately I can't really call my mobile carrier for help, because the phone comes straight from Google via Best Buy and there's no support for it through T-Mobile. I do love my phone and will continue to use Android, but I'm struggling to keep my phone relevant! Any feedback would be gratefully accepted.
