Hi, I have a "query ", I am spanish user with a French rom that it's fine for me with GDR3 (v. ... 155 ... ) and I have a doubt about your batteries... I think that the mobile does not know what battery spent, do "strange things", battery drains randomly and the battery percentage is mostly wrong. Lately the battery lasts longer with the same use, my battery lasts more than a full day except If I use a lot of whatsapp app and others .. (turning it off at night, 4G on, without bluetooth, nfc, one push mail....), but to reach the full day I have to turn it off one or twice, I mean, when I see the percentage around 15 % as I do not trust if this percentage is real, I turn it off one minute or 2 and then I turn it on, and usually I find the percentage of charge above 50-60 % to my surprise, so the mobile support the next day or half day, I'm wondering if the same happens to you??? I realised a hard reset on the phone but the same thing still happens. Conclusion, the battery of the mobile confuses me, Greetings ! (sorry my english)
