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

Thanks guys haha, still don't really know what to do is anyone experiencing the camera flash problems? I am still not sure if it is a software or hardware issue!!!! I don't want to end up having the exact same issues with a new phone or even worse!

handsfull - you are always really helpful to me and i trust your opinions.  when i take my replacement phone out of the box should i let it die all the way first and then charge it all the way up /repeat

 

or do i charge it all the way and then let it die all the way / repeat

 

thank u so much buddy

I'm not handsfull, but if I were you I'd charge it up fully, then run it down fully, but to be honest I don't think it'll make much difference IMHO.

Huh????   6 hours - 2:40 is another 3:20 hours of use says my calculator............   so yes, I think I'm right.

So you think the battery will drop 50% in two hours of use.  I don't think so. In fact, I know that isn't the case.....because a few days ago her phone yielded 12 hours of use and still had 8% charge.

@always

Thanks man, do what you normally do, nothing you do will make a lithium battery sustain a "longer' charge other than charging it up completely.

Everyone:  Lithium batteries DO NOT need conditioning.....many people keep spreading the misinformation on the internet.  It's false.  Draining your lithium cell to 0% is MORE HARMFUL than good....that is a fact.

Keep us updated after you set up as a new phone.  My second phone is WAY better than my first, but still not to standard or comparison to my 4s....not even CLOSE.

@ Jameson

Not sure what math your using, but it's not the math I'm using.  No worries, I'll post my wife's usage to 10% to make it easy for you to understand  

Want to do a paypal'd lunch wager on the results??  I love free lunches.

DO NOT DRAIN IT COMPLETELY!

Lithium-Ion has no memory, see the wikipedia article!

Lithium-ion batteries are common in consumer electronics. They are one of the most popular types of rechargeable battery for portable electronics, with one of the best energy densities, no memory effect, and only a slow loss of charge when not in use. Beyond consumer electronics, LIBs are also growing in popularity for military, electric vehicle, and aerospace applications.^[6] Research is yielding a stream of improvements to traditional LIB technology, focusing on energy density, durability, cost, and intrinsic safety.

we need to stop telling people to completely drain and "condition" their batteries on this forum.

@spydr

I agree completely.....its the web sites who have nothing of quality to contribute and feel the need to make everyone dumber who will read it.

Prolonging battery pack life

• Avoid deep discharge (depletion) and instead charge more often between uses. The smaller the depth of discharge, the longer the battery will last.^{[106][unreliable source?]}
• Avoid storing the battery in full discharged state. As the battery will self-discharge over time, its voltage will gradually lower, and when it is depleted below the low-voltage threshold (2.4 to 2.9 V/cell, depending on chemistry) it cannot be charged anymore because the protection circuit (a type of electronic fuse) disables it.^{[106][unreliable source?]} It is frequently recommended to store batteries at 40% charge level.^[107]
• The rate of degradation of Lithium-ion batteries is strongly temperature-dependent; they degrade much faster if stored or used at higher temperatures and may even be stored in a refrigerator.^{[106][unreliable source?][108][109]}

an update on....me.

Charged overnight.  at 100% when I left the house.  On the train, merely checked email.  I HAVE NOT MADE A PHONE CALL TODAY.  I am now at 94%.

I'm not sure that's completely true... see http://www.apple.com/batteries/iphone.html

Use iPhone Regularly

For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

sure, but people here are draining them completely numerous times in a row, on the advise of people on the forum.

@tim

So if apple Writes it, it must be the truth! LOL.  It's no different than their battery life stats they put out for the iPhone 5....they didn't do the research (teamed up with the fact that its an OLD article they need to delete).

I've worked with lithium cells for over 15 years.

Bud -  

The guy was @ 10% remaining with 6 hours of usage.  (90% used up)

You are at 59% remaining with 2:40 usage.   So over 160 total minutes, you have consumed 41% of your battery life.  That's that's roughly 4min per percentage point.   SIX hours is 360min.   Divide that by 4 yields 90% of your battery will be consumed when you reach 6 hours.

That's EXACTLY where he is!!!!    How can my math be wrong here?

Give me a few days, I'll give you the proof

hello, i am on iphone for 5 years now (iphone, iphone 3gs, iphone 4) and since 28. september iphone 5. i was very suprised, that my new iphone 5 battery seemed a way worse than my iphone 4. i restored from icloud and later i used a clean restore, the battery issues seemed to remain. i had 45% battery left after around 2 hours of using. after a chat with an apple support member, it received a new iphone per express. now i am on my replaced iphone and i think the battery works better now but i am still not satisfied with it. i didnt use a backup as well. the battery of my iphone 4 seemed way better to me. dunno, but it seems like a common issue here :///
