Battery draining too fast

[catlover25]

I have had my Samsung Galaxy 3 about 14 mos. Now the battery is at 65% after just 2 hours. I have had problems in the past several months with the phone getting hot so I have done several power saving steps that I found online. I have turned down my screen brightness to almost 0 most of time and to 'time out' after 15 sec. I do regular clearing of the cache and have force stopped many of the apps. I have checked the battery for bulges and the 'spin test' and it seems to still be ok by those standard so I do not know what the problem is. The last few days I had several error messages popping up when I was on the internet: 'The weather widget had stopped working', 'Google app' had stopped, ATT locker has stopped, etc. It was only doing this while connected to the internet. I went by the ATT store to have a Tech look at it. He turned on the 'location' thinking that would help the error messages but I have since turned it off and deleted a few widgets.

Anyone have any suggestions on what to do next to keep it from draining my battery? Thanks

How low do you normally let the battery charge go before recharging it? (See The Care and Feeding of Lithium Polymer Batteries - you can easily kill a lithium battery totally dead in 6 months if you try hard.)

It varies. I have read several different opinions on it. When I am in the car I may plug it in when it doesn't really need it. I haven't read the article so that may be bad on the battery. Typically the way it has been draining so fast I don't plug it in until it is at around 65%

Well I thought I had already posted another reply. Having computer difficulties also. Great article!! Thanks!!

So If I understand it right I should have a spare battery so I don't worry about keeping my phone charging in my car because I need it for work. That way I can let it drain down further and not keep charging it for no reason. Not sure if that could be the problem. But I never let it get very low until now when it is happening by 'surprise'.
