Q: iPhone 5 battery life is way worse than iPhone 4

iPhone 5, everything turned off (except 3G), brightness to 0:

LOL.

I had to make a full charge around 2pm because it was dead already from the morning 8am. Dead again at 8.30pm. LOL.

My 2 years old iPhone 4 still last for 2 days of standby and around 12/14 hours of my type of use.

My wife's sister iPhone 5 (she got it a month before me):

She's Chinese so she uses the phone constantly lol. A lot of games and I guess she'll be blind soon because she's like 90% brightness. No problem on hers.

Today from 9am to 1pm, 2 hours of use, down to 30%. Went to get a talk with the carrier, they need to keep the phone for 3/4 days before exchanging it... Crap.

Just received my 5th replacement phone today and STILL have the wifi issues and battery drain. This is unnacceptable! I own MANY Apple products and have always standed by Apple 100%. This is by far my worst purchase EVER.

I am looking at getting another replacement as my problems with battery life usage are also still happening even after replacing my phone.

And you think replacing it again is gonna help ? Good luck with that sir

Any other suggestions coolkenny? My friend has the exact same phone I do and a very similar setup and can go way longer than I can while using it more.

So, after getting my latest replacement as stated above, I realized that the phones are exactly the same and have the same problems. I decided to keep my original phone and just ship back the replacement they sent me.

I put the sim card back into my original phone and let the other phone sit in the box to be shipped.

I never synced anything except for my contacts. There was nothing running, never opened Safari, didnt download any apps, no mail accounts synced, etc. etc. The phone was pretty much stock.

Well, at 1am the phone was at 55%. I let it sit in the box on standby over night. At 11am this morning, the phone was at 39%.

No SIM card so cellular data isnt the issue, no connection to wifi because it won't stay connected to my router, no apps running, no mail checking.......then what happened to the battery?????

You do the math

So basically the consensus is its the phone or the actual battery?

I'm having the same issues. With my iPhone 5, battery life is hit or miss. Some days I will have no problems getting through an entire day. Other days (like yesterday) my battery will go from 85% to 30% in just a 1.5 hour car trip doing nothing but sending texts through iMessage. With the same usage patterns, during the first month of my iPhone 4 back in 2010 I always had between 35% and 40% battery left at the end of the day when I went to charge. I understand that with the bigger screen and more powerful internals the iPhone 5 can't achieve that much, but it should be better than it is.

Guys, as i was stating a dozen pages ago (pg. 135 if memory serves me well) chargins through usb IS a big difference. Last time i charged through usb and now i am sitting at 50% with 4 hours 18 min of usage and 22hours 5 mins of standby.

The charge was done with the chinese battry doctor app running. Hope this helps!

Well i charged my phone through usb too this time, from 2% to 100% and it seems to last longer.

Also used battery doctor when charging, only difference this time is that i used a 30min trickle charge instead of 10min/off.

Charged for around 8 hours straight (usually 3-4hours), and the results improved.

first 10-12h standby 4h usage to 1% battery

now 16h 39min, 7h 10min usage and 34% left

strange thing, i'll charge it without battery doctor again soon enough to see if there are any differences.

@speedr0ck, I'm glad you noticed a big improvement too. I think charging through USB has to do with power management, as USB delivers a "smaller" amperage than the wall charger.

Got a brand new phone. This one comes with iOS 6.0, not 6.0.1. I can't even update wirelessly because it is the version that comes with a bug and need to connect to iTunes LOL. Anyway that's great because I was able to try the phone with this version of iOS. Unfortunately the results are the same. 3 hours of stand-by, 50 minutes of use, and the phone is around 70%. I've adapted the locations services (which I never did with the iPhone 4) and I've stopped any iCloud/iTunes Match through 3G but it doesn't help. Now, just have to live with it.

You're assuming that because there is no SIM Card, that the phone is not accessing the network?   I'm pretty sure that's not the case, as you can still make 911 calls.   Just because the phone is not configured with your number and account, you cannot assume it is not doing anything.
