Hi My iPhone 5 is draining battery Power rapidly, i have changed the battery for a New one, however this as not resolved the Problem. Googled the issue, but not Fond a article/ Blog that resolves the issue The phone does Not get warm The phone is not jailbreaked Background Apps / not often used Apps are disabled, Photos reduced (saved to PC) Videos reduced ( saved to PC) Can there be some other Part that using soo much power? Can it lie purely on a software Problem or can it be a Hardware problem ?
This is most likely a U2 fuse on the board at is blown it will case rapid battery drain with good batterys
Really? Searching rapid battery drain in iphone 5 after battery replacement does NOT bring up U2 chip? I’m shocked. Con is right, that is definitely the most likely case. The only other possiblity is a short on the board from some old water damage that you are unaware of. Worth it to open it up and have a look. Let us know what you see. If everything looks good, I’m afraid it is U2 ic chip. It will be hard to find someone willing to replace that for you. Sometimes I give it a shot, but I don’t offer it professionally as a service. jessa
The U2 can be change I no it does require a specialist as its not a simple task The cause for the blown U2 is when you use non genuine chargers
The U2 chip, eh? My iPhone 5 does the exact same thing. I hate that U2 chip, almost as much as I hate the band U2.
I have the same problem. How can i fix it? :( Im so uncomftable with my iphone. Does anyone here can help me?
I found after investigating this issue further it seems a common problem that there is a defektive chip on the mainboard that causes this problem. so if under warranty, get it repaired or exchanged for another. if its not under warranty anymore, maybe you could buy a broken iphone off ebay or somewhere like that, and swop mainboards.
