Battery drains very quickly even when idle

Mon, 19 Mar 2012 15:39:47 GMT

On one day (two weeks ago) I found my phone become really hot and its battery dropped to only about 1x%, I rebooted the phone immediately but the battery was still drained completely shortly after.

After that day the battery keeps draining very quickly no matter what I have done:

- lowering the display brightness

- turning off Wifi

- disabling data traffic

- turning on flight mode

- disabling auto-sync

- calibrating the battery

- formatting the SD card

- even doing a factory reset / repair / upgrade in PCC

I am really desperated and have tried to use a different battery that I seldom use, but still it doesn't help - the battery still drains quickly.

There is something strange about the battery: it discharges very quickly but when the battery dropped to 1%, it can last for quite a long time (up to several hours, depending on my usage).

There is also a problem with the celluar network - sometimes it is difficult to establish a 3G connection after I re-enable the data traffic; the "H" sign in the notification bar doesn't appear and when I try to search for the network provided, nothing shows up or there are error telling me my SIM card doesn't allow me to connect to the network or there is a error when searching for networks.:smileysad:

Is there anything else that I can do? There is still a month till my warranty expires, should I directly take my phone to do a repair instead?

Sorry for my English and I thank you for your help in advance!

Model: Xperia Neo (MT15i)

Android Version: 2.3.4

Build Number: 4.0.1.A.0.283

Baseband version: 8x55A-AAABQOAZM-203028D-64

Kernel version: 2.6.32.9-perf SEMCUser@SEMCHost#1

The 1% in battery can last for a long time

Battery drains very quickly even I leave it idle when I am sleeping

indeed its really bad ,

go to settings > wireless nd networks > mobile networks > network mode > gsm only..

try this , you wont be able to use 3g in this but try and notice the battery..

also , charge your phone to a 100% , emove the battery for 15 minutes , re-insert it , and agin charge...

slim, switching to gsm helps to people who have poor battery life and they want to increase it

but in this case

hey, may i know what these numbers are at the top left corner of the screen ??
some battery saver app monitoring your batter?? if yes then just uninstall it right away

Thanks everyone, I will try these

And yes, it is a battery monitor app called "Badass Battery", I will try to uninstall it and see if that helps too

Hello all, I have tried Johan's suggestion but unfortunately it seems that the battery still drains very quickly.:smileysad:

I am thinking about buying a new battery to see if it works.:smileydevil:

You should not have to buy a new one.

Since you write that you've already tried to factory reset and repair the software I suggest you go back to the store with the phone and see what they say about it. They might lend you a different battery/charger so you can confirm if the problem lies with the phone, battery or even charger.

Hi,

I have a Xperia Neo MT15i and suffering similar problem.

Upgraded to ICS a couple of weeks ago and since then I am experiencing the following: battery drains much quicker than with GB (with moderate use I hardly get 1 day, whereas with GB I had 2 full days, no problem); slight lag in running some apps, specially noticeable in some games; some overheating in the back of the phone.

I have tried some of the tips suggested in various posts (e.g. remove battery when at 50%, then recharge for 5 hours, repair sw through PC Companion to have a fresh new install of the OS) but battery performance is very poor, to say the least.

My ICS version is as follows:

Android version: 4.0.4
Baseband version: 8x55A-AAABQOAZM-203028G-72
Kernel version: 2.6.32.9-perf / BuildUser@BuildHost #1
Build number: 4.1.B.0431

I have read in different sites from other users that previous baseband versions (56 and 64) have much better battery management, but I would not know what that means or how to fix it.

I am completely stuck. I really like the phone and enjoy the ICS experience but I am getting rather frustrated with this battery issue.

I would appreciate some help.

Thanks in advance for your advice.
