That $15 has already been wasted on a totally unnecessary product.
The geniuses will a lot of times hook your phone up to the diagnostic to check the battery. Some will just freely replace it based on your complaint but most likely they will test it first and guess what? If it checks out "ok" on their diagnostic they will most likely not replace it and tell you to disable all your "smartphone" settings.
Its not unneccesary the first time you forget and put your iphone in the same pocket as your keys.
Never assume.
The first 4S I bought for my wife had horrible battery life. Took it in, the genius replaced it.
The new one is so much better it's shocking.
Didn't read the topic, but I would say this is absolutely true. My battery life improved significantly after I exchanged my phone out. I had a max of 5 hours and thats only if at least an hour of that was me playing pandora. Now I use it the exact same way but get much better battery life
Will Apple replace the battery if the 4S was purchased through Sprint? Thanks.
One of the joys of owning an iPhone is that Apple will honor the warranty no matter where you bought it from (this includes eBay). As long as the phone is still under the 1year warranty and the problem is covered under the warranty, Apple will replace it no questions asked.
Just wanted to add my two cents. My 4s (which was purchased factory unlocked at full price from Apple Canada online) had terrible battery life and constant/repeated loss of 3G signal. I followed all the usual troubleshooting steps, including restoring as a new phone and swapping the sim. I took it to the "genius" bar yesterday. They ran their diagnostics and told me that the battery was functioning normally. They thought the constant signal dropouts were due to a software problem and insisted that they would be fixed by doing another restore (which I had already done). They refused to exchange the phone, even after I spoke to a manager. What I landed up doing was buying a brand new 4s in the store and returning my original 4s online ( the store refused to accept a return of the phone because I had bought it online). It appears that my new 4s (even after one night) is vastly superior in terms of battery life, even though I restored it from the backup of the old 4s which was running "corrupted software" (according to the "genius"). This is my longwinded way of agreeing that replacing a phone with bad battery life might be the only way to solve the problem, and I am not convinced that the battery problem is software-related.
