Replaced Battery, Constantly Reboots and unchanging battery percent

Sound like a bad cheap battery let us no how you get on with the ifixit battery

I have one in my shop right now doing the same thing… Battery percentage does not change and the phone reboots constantly with the original battery and with a new one. Originally the phone came in with a bad power button so we changed the Power/Mute Lock/Volume button flex ribbon … which appears to have caused the new issues.

May try another ribbon just to eliminate that as the cause but Ive personally repaired hundreds of 5 series with bad power buttons and never had this issue afterwards.

WEIRD!!!

Will post results.

Hello Guys,

FYI, I got exact same problem.

Battery level indicator freezing, never changed value till phone reboot.

uncontrolled reboot when plugged in in order to recharge. (mac or sector)

Solution:

Discovered that my Second hand iPhone had a chinese battery inside,...

After placing a certified battery inside, problem solved.

so,...

Cheers,

Replacing the battery will help with a depleting battery where the phone constantly dies after little use.

For a phone that blue screens or constantly reboots and doesn't cahnge the percentage of power, this is the power module or charge connector that has become damaged so will need replacing. Wasn't too expensive for a phone shop here (around £35 for dock connector replacement which was diagnosed by Apple, which I found after paying £40 for a battery replacement previously!!!!).

Hope this helps. It has solved my charge, blue screen, rebooting and battery percentage not dropping issues.

Thanks for getting back to me so sorry to hear about your phone. I got a dud battery as well, not exactly the same I am waiting on a new battery today. I pray that I don't have the same end result. I spent so much money on phones this year, I had my phone stolen, the one I purchased ended up being a dud and now what I've done to this one. I'm no expert but it was really easy to change out the battery, I'm very disappointed the battery was a dud. Again thank you so much for explaining.

Hi there, I was facing exactly the same problem that has been discussed here.

After replacing my battery on my iphone 5 the battery panel got frozen (it updated

only when restarting the phone) and the phone rebooted constantly when it

was charged.

Here is my solution: I had my battery being replaced by a local shop

(NOT an authorized apple dealer) and when the problem occured I

brought back the phone multiple times to the shop. The guy in the

shop was quite collaborative, so he tried one battery after the other

(there were original apple batteries, at least there were packed like that).

Anyhow, after putting in the third or forth battery the problem stopped.

So, my solution is, replace the battery, and if that doesn't work, send back

the battery and have it replaced by a new one and try again. It seems

that these batteries are somewhat fragile.

Good luck with your solutions.

Hey guys, I created an account just to post the solution I found to this issue.

Background: Changed the iPhone battery to a new one

Issue: iPhone would not ready battery percentage, it would always freeze and after a while when battery did died, it was constantly restarting with a white screen for 3 seconds and stuck in this loop. I was able to restore and back up when I got lucky and the phone stayed on, but after a while the issue came back and the restart loop of death came one.

Solution: I read on the comments here on the tape piece on top of the battery conector

There is a small circular connection just bellow the battery connection (under the frame/once you take out the 2 screws), This piece gets loose, this is where you need to make sure it is properly making a connection to the metal just below (another circular connection), I noticed this was moved and after correcting it, my iPhone came back to life and upon connecting it with a cable it showed the red battery/need charge sign. Now the iPhone is working normal and reading battery percentage..

You can see the connector thing I mentioned here just bellow the knife, its the round one with the sponge on top (http://www.encorenews.ca/wp-content/uplo...)

Hope this helps and all the best to all of you!

I've done the same to my iphone 5. Replaced the battery and must have scratched something. I was extra careful as I just spent 2 days soldering together a complicated kit, but I guess I wasn't careful enough!

Went to the Apple store today and they checked out the phone. Told me the battery reads as null. Told me there was logic board damage but no further info. Guy suggested to wait it out for a while as its more or less working now.

Its annoying but at least I know the new battery is keeping a longer charge as my old one was draining quite quickly.

Hi guys, i was also having this boot loop issue whilst having a battery percent that wouldn't rise or fall, after several attempts I found that simply tightening the screws on the battery ribbon protector stopped the boot loops but didn't fix the battery percentage issue.

After taking the iPhone 5 to a trusted repair shop which is the only place the phone has been repaired (screen connector fixed), they ask me when I had my battery replaced? Obviously I have never had the battery replaced :/ I asked why they thought this, they replied with, the battery has a small gold sticker on it, this isn't normally on apple batteries? Can someone confirm this for me, as if my battery was swapped to a knock off battery, it was clearly swapped out by the repair shop and could be the result of the battery percentage problem, the knock off batteries!

Another cause of the boot loops Which i discovered myself, is the new batteries, wherever they come from, usually dont have a foam sticker on top of the connector.

YOU MUST PUT ONE ON!! - in my case i didnt have one so covered the connector with electrical tape. Otherwise the logic board will detect interference and wont do a full POST.

and hence create a boot loop.

I had this same issue replacing my 5s battery today, after reading your comments I found that it rebooted 6 times, and then that was it. Then the battery showed 6% and did not change after being on the charger all day. So I took it apart again, and added the electrical tape to the top of the battery connector, since my replacement battery did not have the foam on top of the metal connector. As soon as I turned it back on and the battery showed 83%, it did the reboot 6 times again, so I'll keep my fingers crossed, but it seems ok now. Thanks for all the comments, they certainly helped me.

After changing my battery from the apple store, i started having boot loop problem. So i went to apple and they offered a simple solution: turn on your iphone by pressing the home and power button simultaneously. Although my battery percentage is frozen but i've successfully gotten out of the 3 minute boot loops

Hello,

I had same issue with iPhone 5c, after replacing the battery I would experience the phone rebooting randomly and never changing percentage until a restart.

I have since fixed this issue and I believe the cause was the replacement battery I had was 1560mAh while my original battery was 1510mAh. Since replacing with with a 1510mAh battery the phone no longer reboots and the percentages increases/decreases correctly.

Hope this helps.

I also had the new problem of rebooting and unchanging battery charge levels after battery replacement, (although greatly improved battery life), the problems were fixed with installation of a second battery. My 5S battery has 3 terminals, call them ABC. I had ~4VDC from A to C, but A to B or B to C were 0V, and infinite ohms (using either polarity, note that measuring resistance on a potentially energized circuit is only meaningful if it's actually an open circuit as was mine). The 3 conductor flat ribbon cable goes to a tiny circuit board on the battery cap, likely something was wrong there as the 3pin flat ribbon connection to main board connector was good. My good battery measured a few volts A to B (about half the voltage of A to C), but it should not read an open circuit as the bad one did.

I had the same problem but was able to fix it. Try this:

The problem seems to be with the battery connector onto the mother board. The reason it is looping is because it doesn't recognize the battery. While I had the phone open, I disconnected the battery and plugged the phone into the charger and pressed the on button. The phone continued to loop as it was doing before with the battery connected. While the phone was looping, I reconnected the battery a few times until the phone recognized the battery all of the sudden. After this the battery seem to work just fine. I quickly backed up the phone just in case (you should definitely do a back up before doing all this). Hope this helps.

I spent 28 dollars to replace my battery, IT WORKED! :)

I have a damaged SE. same issue. reboot every 2-3mins ..stuck at 1%. what's the equivalent chip's name of FL11 on Iphone SE?

thanks.

After I replaced my battery my iPhone kept restarting every 2-3 minutes, not charging more than 13% etc. I thought that the battery is damaged, but the problem was that the contact from battery was a bit oxidezed. A little contact spray helped me solve the problem and the phone works now perfectly.

I Had this same issue when I bought a new battery. I charged the battery right up and then took it out and shoved it to the side for a week. Continuing to use my old battery, I then switched the battery back and it hasn’t restarted once and charges up and down perfectly (calibrated nicely). One think I did notice too was the ribbon cable wasn’t bent like my original apple one it needs to fold twice, I also did this but I can’t see that having much of an impact.

Hope it helps!

Hello, maybe late but i hope it will help someone

this happened to me 2 times, one time with an iPhone 6 Plus and the second time with the iPhone SE, just after the battery replacement the iphone started to restart every 2 min and when i put it on charging it get stuck in the same percentage.

What i did to repair it is change the charging flex, i don’t know why but this has worked in the two iPhone’s.

I fixed my issue by using Electric Contact Spray. It seems that either phone’s contact plug or most probably battery’s jack oxidized and didn’t make perfect contact. After I sprayed these 2 jacks it worked like charm.

Ok, in my case, one of four micro resistor was losed. I bridged , because is not possible for me another choice, and seems who it work. I will advice against if it catches fire.

Thank you for your aknowledge.
