I have a Sony Xperia, and I use 2 battery savers!!
- Easy Battery Saver For Android, you can choose the mode and what services you want running or customise your own plan. It also tells you what has been using your battery and your remaining battery capacity. The mode I am on at the moment gives me 60% extra battery life
- Green Power Free, like Easy Battery Saver but is more time planned with what will turn on/off and when.It manages your data/wifi more than anything.

They are both free I find they work well together and my battery now lasts 2 days with me going on Facebook/Instagram for 4 hours, playing music for 1 1/2 hours, texting for 1 hour, playing games for 1 hour!! Hope it helps
