Battery help

[alinachao]

Sometimes my razr XT912 battery gets heat. But when I took it to the carrier, they cannot find out the problem. Found a battery repacement here. But I'm not sure whether it's the battery problem or other parts problem. If the battery issue, is it easy to replace it? In fact, I really hope the carrier will change a new one for me.

Phones get warm when they are used for extended periods of time or when the battery discharges very rapidly. I think this is pretty standard for any phone.

Really? But what about if it's a little frequently?

±1 to what Fury says. The phone can get very warm if it is downloading files, looking for location or struggling to maintain a signal connection.

I have felt mine get warm while I'm my pocket not being used only to find it was trying to get my location through gps.

Are you sure it is the battery generating heat rather than just being heated-up by something else? You should first try to establish a cause and effect relation when the "sometimes" happens. For both my old HTC Aria and my current Razr M the worst case heating situation was/is when charging the phone in the car while using the GPS and Bluetooth. Right there you have all the elements that contribute the most to generate heat in a phone, due to the relatively high electrical current going in or out:

- Pumping current in the battery
- Screen constantly on
- High processor and GPU activity
- GPS and Bluetooth on

In cases like this I'd say it is normal to expect the temperature of the phone to raise significantly. The next worst case I have observed is when playing games. Again, the combination of high current drawing on the battery, screen always on (possibly with high brightness setting) and high CPU/GPU activity all contribute to generate heat.

Thanks a lot. I'll find out the problem first before repair it.
