If you’re having this issue check out the #batteryguide . Original Post: OK I’ll definitely not win this… My phone was 100% this morning at 7:00. I checked my mails and the forum, played some frozen while waiting for my daughter but not a lot. It’s now 11:00 and it’s down to 50%. Don’t like it… I…

Did you try the OS Monitor I linked? If it’s a software problem, this might help you find it.

I did try this a few times but saw no improvement. Is this likely a battery or software issue? Battery behaves normally but when it gets below about 40% at some point it will rapidly lose charge and go to 0% in about 5 mins.

Sorry for the late reply. I’d say battery - I’ve had this on multiple devices once the battery gets older (in terms of the number of charge cycles, or in some cases for devices that typically are plugged into a charger most of the time). Replacing it made the problem go away, but obviously your mile…

I bought a new battery, and i tried hardly to use this brand new one on the best way… and my FP still runs 7-8 hours before getting hungry… and if i try to use WiFi or 4G… it’s getting as hot as battery is getting empty… I’m quite upset right now. I don’t know how long my FP2 will stay in my pocket …

Sounds like a defective or bad software. Get in contact with for support! While waiting for a response, you can try a factory reset. Or disable the phone and check that all modules are sitting right at their place.

To “Greenify” I have used it for several months and was confident it would extend my batterie´s uptime per charge. One charge would either way last at least a day or more. But after some months as I did not even think of Greenifie´s background actions anymore my phone started very strange things. I…

Thx a lot for that information and very thorough explanation.

I have the same issue… Phone becomes hot (above the battery) when I use the Internet (3G, 4G, wifi…) and drains very quickly. But my phone is completely new !! I did kickstart the battery, checked the SIM cards, the SD card, followed the battery guide, but nothing changes. What should I do ? A 55…
