Having recently acquired a samsung galaxy s android handset, I proceeded to install all the apps that I had installed on my htc legend. One of them was the juice defender app, which worked quite well on the legend.
Soon after I installed the app, I noticed that the battery would drain quite quickly. Within about 4 to 5 hours the battery would be totally flat. As soon as unplugging from the charger, the battery would be down to 80% within about 10 minutes.
Thinking there was a problem with my phone, I began to check all my settings. I then realised what the problem was when the juice defender app was starting really slowly. In fact, the app was causing the phone to really lag badly.
I immediately uninstalled the app and believe it or not, my
battery life improved after uninstalling Juice Defender.
You might want to try this if your galaxy s suddenly drains battery like there’s no tomorrow. Now my battery lasts 8 hours plus like it should.
