Battery drops to 1% suddenly

hiren_chauhan — Tue, 10 Apr 2012 10:42:11 GMT

Hi there,

I purchased brand new Xperia Active before a week and it starte showing battery related problem since then. When my phone shows battery level of 15%, it suddenly drops down to 1%, followed by phone shutting down. I have not rooted my phone. It is running on Gingerbread 2.3.4 and build 4.0.2.A.0.62.

Managing on 1200 mA is anyway becoming tough task for me and above that this issue is really irritating now can anybody there has solution for it?

hi Note the battery % level Then take the battery out of the mobile and reinsert it after 2 minutes and see if there is any change in the % if yes then most probably your problem is solved

Hey, I have tried doing it, my battery level was 35% when i removed and now after reinserting, it unbelievably shows 38%, i wonder from where this 3% hike came in :smileyconfused:.. any idea?

Anyway i am waiting my battery level to reach 15% now and lets see if shuts down again.

Nabeel, this time when it reached 17%, it drained off, so problem still persists what's the next step? The phone which i used to love before a week is not not proving worthy becuase of this battery stuff..

i tried this....

complete recharge upto 100% , removed the battery for 5 minutes.. re-insert it...

battery was at 85% , charged it again to 100% , never got the problem again..

Just to update you all guys, even after using the all the above tricks , battery problem keeps on coming. And c'mon you don't have time to remove battery every time, charge it till 100% and let it drain completely before it drain down till 0%. If you don't do that, it's rhythm gets disturbed and battery again starts showing it's flaws. Because of this problem, i really have missed so many important calls. Battery sometimes shows 15%, 17%, 10% , 5% and suddenly to my surprise, it shows 1% followed by shutting down of phone. Then all you've have in hand is dead scratch proof, water proof phone Not happy with commitments made by brand like Sony. I guess while showing all the promising videos, they should also mention one line about battery

But i never faced this problem....nor does slim and Eske

One thing i doubt is do you have task killers, battery / juice defenders ( same kinds of apps) etc etc ?

Because surely only such apps could interfere with main battery app

My advice is to repair your software using pc comapnion and never install such apps please..... no managers and juice please

it happened just once and after doing what we suggested , it never happened again. you can get it checked from the service centre and get the battery exchanged.

The actual capacity of a battery decreases as the battery ages through an irreversible fading process. This capacity loss occurs both with active use, correlated with charging cycles, and with inactivity through self-discharge. The device may even come with substandard batteries. However, the amount of loss is linear with time and accelerates with increasing temperature. Smartphones do not typically employ sophisticated techniques for estimating the usable capacity with the basic solution basing on simple charge cycle estimation and then using an offline calibrated lookup table to find the state of charge or battery level given the charge cycle.

Battery level or State of Charge (SOC) estimation in modern smartphones cannot capture the usable capacity of the battery run time, and thus have unreliable SOC estimation. This inaccuracy manifests as sudden jumps in the battery level, and can result in unexpected shutdown of the device.

Therefore, there are two issues; (1) The battery capacity is reduced, and (ii) The device is unable to estimate the capacity loss. The detail about this can be found in the following paper.

Sudden Drop in the Battery Level? Understanding Smartphone State of Charge Anomaly.
