Does anyone know if it is safe to keep the charger cord attached while changing the battery? The goal, of course, is to prevent a hard reset. (Obviously, all data should be backed up to SD card first.)
Is there a post somewhere that outlines the recommended steps for the battery change? (Search has not yielded one.)
Thanks,

Hi, I recently replaced my battery with a higher capacity battery bought off ebay for $22US del from HK to UK in 5 days. search for ezipda, later bought one for an Ipaq for same price.
The process of changing over took 5 mins, BUT!! I would not recommend having it plugged in and changing batt. You may be shocked by the result (pun intended). I cant remember if it did a hard reset but dont think it did. As long as your back-up battery is charged and u are quick dont think there should be a problem.
Unscrew the screws and get a wide thin blade and go around the edge of the case, I didnt and caused a few marks ont he edges! There are a number of clips that pop open quite easily. The battery is held in place by double sided tape, use the the same blade and carefully prise the battery up. Replacement is a reverse of the procedure, the only tricky bit is the connector is quite small and a bit difficult to locate but not too bad.
Hope I have helped. :lol:
Thanks, BadgerBoy1.
The backup battery is the key, but how does one determine if it is working and charged? I've searched all over the system for an indicator of the backup battery, to no avail.
That begs the next question: If the backup battery is bad, where is it, and can it be replaced?
So the other day while minding my own business, I pulled out my phone to use it's calculator for some accounting work. Just as a side note, I keep my phone in my front pocket, and do not wear skinny jeans. When I pulled it out, I looked at the back and it had a crack going down the center of the glass with a slight bulge where the battery is. As soon as I got home, I pulled the battery out and saw that the backside was bulging outwards. It bulged so bad that it managed to crack the glass even with one of those gel-like protectors on it . I tossed it aside and put it my spare battery, which should have been good. This is where the interesting stuff starts happening.
Slowly but surely, the lifespan of my battery would get shorter till the point where as soon as I unplugged it, it would die. It got so bad that It would die around 95%. When it would charge, the percentage would vary a lot, making a very interesting graph in the battery app I have. Not only that, but sometimes when I would restart my phone, it would be a completely different percentage than it was before. On top of that, when the phone would die, it would be at a different percentage than when it was still alive. I would have to plug it into a charger in order for it to start up again. If I did not, it would sometimes get into a boot loop where it would say google, turn off, then turn itself back on, rinse and repeat until I held the power button forcing it off.
After I changed the battery, I rooted it and put the Carbon nightly rom on it, but in order to eliminate possible problems, I did do a factory reset to the phone to make sure it was either of those.
Now I did put a "new" battery from ebay in it, but I am still having the same issue. However, the battery I believe was not new because it still had glue on the back of it from a previous nexus. My actual new battery should be here tomorrow I hope.
Could there be a problem with the batteries, or could there be a problem with my logic board? I have tried two different chargers, the LG one provided with the phone, and a rocket fish wall charger, same problem. Attached are two different pictures of the battery graph. The sharp drops are where it dies, and the sawtooth wave is it on charge. (Don't hurt me! I know I'm not supposed to post outside links, but this is absolutely necessary for you wonderful people to help me! Just remove the space in the link and it will work)

2018 may be late in the game to become a new owner of a OnePlus 2 phone. But here I am. My main phone at present remains a Samsung Note 4, and I'm trying to get a feel for how this old (but not as old as the Note 4) phone can be repaired. My issues are a mix of battery, possible circuit board, and other problems / eccentricities.
The phone was given to me non-working. I have a minor-league reputation for rescuing phones, so thought I'd try this one.
First, I had to get it up and going. Nothing worked initially. I wasn't delighted to find out the battery is only accessible after removing two covers and about 30 microscopic screws. I reset it by pulling the small "plug" at top center-right and the phone decided to allow me to boot. I immediately (per instructions I found elsewhere here) went to fastboot and wiped the cache.
I did manage to install TWRP and the latest (as of a few days back) version of Lineage 8.1. But then the problems began again. The phone would suddenly, after charging for a while (and reporting a battery that was nearly charged), shut down. No charging icon showed on the screen.
Fast foward. Today, I got a cheap knock-off battery in the mail. It intially worked and I got it nearly charged. But after more spontaneous reboots I noticed something odd; in TWRP, the battery said only 50% charged while in Lineage it said 97% charged. So once again I wiped the cache and this time the ART/Dalvik cache as well (pointless, but ya never know).
This did get the two percentage reports matching up. And initially it got the phone working again. But alas, once again, the phone started the shutting down.
Currently, I'm leaving it overnight to charge - if in fact it is charging (how does one tell)? If that doesn't work, I'm thinking about using Odin to totally reflash the original version of the operating system.
Any other ideas or input - including laughing at me for bothering with this - is permitted.
I will say that the engineering of this phone compared to the older Note 4 leaves the Note easily the winner; to take its battery out is a matter of 20 seconds. Really not impressed with my OnePlus experience so far...
Thought I'd update things. After spending a day on sites (here and on the official OnePlus community boards) I tried any number of fixes. I'm reasonably convinced the only way to somewhat consistently start my particular OnePlus 2 phone is to:
1. Open it up, thus voiding the warranty (hehehe.... by now that's void anyway).
2. Unplug the battery's small plug at upper right-center of battery (a fingernail works fine, but do make sure the phone isn't plugged in!)
3. *Leave the back off* or at best gingerly snap it on but without attaching the screws. (Every time I did so, even after extensively using the phone while it lay on my sofa's arm and rebooting it numerous successful times previous to replacing the screws, the phone refused to reboot.)
4. I also cleaned the usb c socket with a wood toothpick and was a little surprised at how dirty it was; I did the same in a minimal way to the battery contacts.
5. I found no real use to having the actual OnePlus charger; I used it a bit but my best results came from the Samsung charger and a new (though cheap) usb c cable I nabbed via ebay.
Today I did get the phone going and intentionally wiped Lineage and installed the latest (2017) version of the OnePlus2 official os. It went on fine. I rooted it, installed apps, and (as mentioned) repeatedly shut down and restarted the phone, which promptly restarted with only a 3 second lag. I did this 5 times because one thread I found suggested this was an official OnePlus suggestion. (I rolled my eyes but did it anyway.) Played with the phone a bit, then shut it down again and screwed the back on. As noted, the phone suddenly wouldn't turn on again.
In summary, I'm not sure if this phone can be meaningfully resurrected. If I knew where what may be a short in it was, I could possibly replace that part. But I have little idea and am not quite the geek enough to sort that out. I am guessing at a short because without the lid or screws, it wants to work. It wants to be a good phone for me and I'll keep toying with it for a while longer.
Any suggestions appreciated.
Third post is a question for others:
Has anyone else experienced their OnePlus 2 working fine *without* the back cover screwed on, but as soon as it was screwed on the phone stopped working and wouldn't start again? And, if so, did they ever sort out why?
I'm going to make this a separate discussion.
Hey. I experienced the same symptoms with a "official" replacement battery I found online. Random reboots over and over again until I couldn't even turn it one anymore.
TWRP was always showing different battery percentages than OS.once I put back in my old but original battery that came with the phone it turned on again and it works flawlessly again.

This is something I've read, and may well do. It also, however, raises another thorny set of issues re battery calibration. I understand that sometimes new batteries have to be "calibrated" by being charged, discharged completely, charged again, discharged completely, and charged yet again and discharged. After that, things are supposedly going to run right. Trouble is in my case, the phone doesn't want the battery; it keeps stopping completely and not restarting. Either the battery stats are wholly inaccurate (says around 57% charged during those brief times I've had it up) or I need to go with your idea. Trouble is there the original battery from this phone is dated 2015; I hope it has anything at all left to give.

I'm trying this in desperation. The phone has gone completely unresponsive at this point, and I'm looking at having a technological paper weight. Hope I can resurrect it but the odds are not good.
Some progress, some regress.
Here's what I'm seeing. I can get the phone up and running again after extensive recharging. As long as I leave the back of the phone off - that is, both the inner and outer backs - it seems willing to keep running. As soon as I snap the inner back into place, not even with the screws yet, the phone locks up. Soon after, around 10 to 20 seconds, it shuts off. Sometimes it will restart and other times it won't for a long time, even after unplugging and replugging battery.
Has anyone else run into shorting or grounding issues associated with the back (inner, the one w/ 18 screws) case?
I am now back to a dead phone. A new (3rd party) battery is my current hope... charging it for over a day now has not yet led to the phone showing any sign of life.
One other question: I know both this cable and charger work, but as they are not the "original" OnePlus charger / cable combo, could that be the difference? I'd appreciate it if there is any clear evidence regarding this question.
The below article raises a disturbing possibility, based on the reality that OnePlus cables and chargers are - by OnePlus' own admission - non-standard and possibly could harm other electronics. But on top of that, and not well explored in the article, is whether or not OnePlus' charger/cable combo might even be damaging to the OnePlus 2 (and other OnePlus phones). They "assure us" this is not the case. Hmm.
https://www.androidauthority.com/oneplus-responds-to-bad-usb-type-c-cables-658048/
I thought I'd update this thread with what may be the final installment.
I invested $70 in a highly bent but somehow still working second OnePlus 2 phone off ebay. (The guy had a great fall on a log story as to how the phone got bent.) Long story short... I gambled and won. That is, I gambled that the innards of the second phone would go into my first phone and that the first phone's screen would work. YES. And so, after playing amateur phone repairman, I have myself a OnePlus 2.
So many questions. Going to peruse this board now...
I just replaced the battery and screen on my LeEco Le Max 2, and this post will detail the process. Hopefully it will be helpful for someone who is considering to replace their screen and/or battery.
Consider buying an extra screen
There are a number of people who have reported breaking their screen as a result of replacing the battery. I highly recommend that you buy a replacement screen if you intend to replace the battery. Unfortunately while removing my screen I also created a few dead pixels (which you'll see later). With all that being said, it is definitely possible to remove your screen without damaging it. I suspect that next time I will be able to remove the screen without damaging it.
Tools required
- small philips screwdriver (from Jeweler's kit)
- thin prying tools
- suction cup that tightly grips screen (you'll see the one I used later)
- heat gun or hair dryer
Onto the replacement procedure
Before you begin, make sure that you have plenty of time to commit to the replacement. It took me about 2 hours to swap the battery and screen. You should also read this full post before attempting to remove your battery.
Remove any sim cards in your phone and turn your phone off.
You'll need to heat up the perimeter of the screen on your phone. This can be done using a heat gun, however I manged this using a hair dryer. I spent about 10 minutes heating up the screen before attempting to remove the screen. Note that as you're removing the screen you may need reheat certain areas of the screen to loosen up the adhesive that secures the screen.

"lightbox_toggle_sidebar": "Toggle sidebar"
}
Next you'll want to apply the suction cup towards the bottom of the screen. Ensure that you have a solid grip on the screen.
I pulled the suction cup away from the screen, and began to notice that the sides of the screen were begging to come undone. I used a prying tool to sliced the adhesive that was holding the screen in place.
Go around the edge of the screen very carefully until the entire screen is removed. Remember the screen is glass and will break if it's flexed too much. My advice would be to go slow and use a lot of heat.
You'll need to remove two small screws behind the screen in order to disconnect the cable which connects the screen to the body of the phone.
Then disconnect the screen ribbon from the phone.
There will be an additional 15 screws which you'll need to remove in order to get to the battery. If you are just replacing the screen you can skip ahead to the section where I connect the new screen to the phone.
With all of the screws removed, you can pry the shield away from the back of the phone. You'll need to be careful, as a ribbon is glued to the back of the shield.
You can see the glue locations for the ribbon on the back of the shield. With the shield removed, you can now finally access the old battery.
Disconnect the ribbon that is right above the battery. Near this large ribbon will be another smaller ribbon that connects the battery to your phone. Disconnect the battery from the phone.
Now you can begin to remove the battery.
Important note from an XDA user
Jaki1122 said:
In the attach photos, you can see on the glue band (or whatever is called) a wider zone close to the motherboard. That is because you are supposed to grab that and pull straight. Then the glue comes off and the battery pops off nicely without being bend and with 0 danger. For this procedure you need to take out the motherboard entirely, which is pretty easy and quick. Take out the SIM tray (I always forget about this one ), disconnect the few connectors (vol and power buttons, fingerprint, USB Dock and the coaxial cable on the right), then 2 screws and its just comes out. After this the end of the glue band is clearly visible and easy to take and pull. Also, and this applies to all phones, you can use isopropyl 99% to weaken the glue (also useful for cleaning PCBs and fix water damage). Another note: you should always avoid bending a Lithium battery like in the photos, heat it to 70 degrees Celsius to weaken the glue and take it out as straight as possible.
Note 2: FOR LE ECO LE 2 USERS: The battery is mounted exactly like the Max 2, BUT you need to take out the USB PCB and speaker on the lower part of the phone instead of the motherboard, given that there is where the "puller" is. Why is it different to the Max 2 if the rest of the phone is identical? No idea... Maybe a brainfart?

Be very careful not to puncture the battery as you remove the battery. The battery is glued into the base of the phone. You can see the two major glue strips in the following picture.
Place and secure the replacement battery.
Reassemble your phone. Before you put the new screen on, I recommend testing the original screen to see if you damaged the screen during the process.
You can see a few new dead pixels on my original screen. This happened as I was prying the screen open, so you'll want to be very careful as you remove the screen. Do not stick your prying tool too far in or against the screen. This damage is something I could live with, however since I have a new screen I'll go ahead and put it on. Turn your phone off before attaching a different screen.
You'll want to connect and test the new screen before proceeding.
Hopefully your new screen is working. Turn your phone off again. Now you should do your best to remove the old adhesive that was used to secure the old screen to the phone. However, you should only do this if you have new adhesive to secure the screen in place!
Your new screen should come with an adhesive template. Remove the outer edge of this template which will be placed on your phone's body.
Now place the adhesive template onto the body of the phone. You'll have to push down such that the adhesive has been firmly placed. Remove the template such that only the adhesive around the perimeter of your phone remains.
Connect the new screen's ribbon to the phone, and secure with the two screws. You can now firmly place the new screen into the phone. You'll want to firmly press the screen into place around the edges.
You'll want to keep pressure on the screen while the adhesive sets in place. I used a few pennies placed on the floor to give clearance to the rear camera. Then I placed the phone on the pennies, and heated up the screen again. I believe the adhesive will cure faster and stronger onces it's been warmed up.
I then placed a textbook onto the screen with a 10 pound weight, where I let the phone sit for an hour or so.
Enjoy your newly replaced battery/screen and hopefully this has been helpful!
AccuBattery stats for the new battery
I'm now on the second charge of the battery, and I figured you may be interested in some of the stats of the battery. You can see that despite the battery being labeled 4100 mAH, the estimated battery capacity is only about 3000 mAH.
Frequently Asked Questions
coming soon
Edit June 7, 2019, I think we can conclude that changing the battery capacity as detailed below doesn't do anything
Updating battery capacity in Lineage based roms
This is in regards to this post https://forum.xda-developers.com/galaxy-s3/general/fix-compiled-powerprofile-xml-file-to-t1732722
I don't think that updating the power_profile.xml https://github.com/LineageOS/androi...works/base/core/res/res/xml/power_profile.xml does anything really. However if you want to change it to a new battery capacity, this post will explain how.
I edited the default power_profile.xml to reflect the new 4100 mAH battery (there are many doubts of the real battery capacity). I then compiled the power_profile.xml. The attached power_profile.xml is the compiled version.
1. Boot into recovery and copy /system/framework/framework-res.apk over to your computer.
2. Make a backup of this framework-res.apk
3. Open framework-res.apk on your computer using 7zip.
4. Navigate to res/xml/
5. Delete the power_profile.xml
6. Copy the attached power_profile.xml into the location where the previous power_profile.xml file was. Note this is a compiled file, meaning that it is not in plain text and you can't read the inside of the file.
7. save the framework-res.apk
8. Copy the new framework-res.apk over to /system/framework/
9. Reboot your phone.
You can use the following command to pull a csv of your battery stats while your phone is connected to your computer and running lineage (other other OS). More info here https://developer.android.com/studio/command-line/dumpsys
Code:
adb shell dumpsys batterystats --checkin > bat.csv
which will create a comma separated list of your battery properties. The one related to the specified capacity of your battery has the section identifier pws. Open bat.csv on your computer and search for pws. Before doing this change it would show up as 3100, and now it shows up as 4100. However, I have not noticed that this did anything different with the battery behavior or estimated battery capacity. The only thing this appeared to do is now that when I open AccuBattery a different manufacture capacity shows up.
Six month battery review:
I have 120 charge sessions, and probably only 1% of those used Quick Charge 3.0. AccuBattery shows estimated capacity of 3,065 mAh. The battery has been strong so far. See attached screenshots.
Hi, great guide, but when i try to download the power_profile.xml you uploaded i get an error.
I'm thinking on buying a new battery to replace it (and buy a screen just in case) because my current one its not calibrated and i cannot find a way to calibrate it, it says that its got 1800mah but it can actually hold 3000+.., the real capacity its really 3000-? i have seen people that say its around 3800~ can you confirm?

Try right clicking power_profile.xml and doing a save as. That just worked for me.
If it's a software bug, then EUI should help.
I was in a similar situation where my phone was 1.5 years old, and my estimated battery capacity was around 1700 mAH. I tried calibrating my battery (on lineage), and it did not work. As soon as I put this battery in, on the very first charge, the calibration appeared correctly on lineage. No sudden battery % drops or other weird behavior.

Did you fixed that problem? Or your battery was actually 1700mah? Because mine is not..
Also any updates in the real battery capacity? I've thinking on changing the battery right away, but if its only 3000mah its not worth, whats the charge current when it reaches 100%? it should say that in accubattery

My battery was failing and rapidly getting worse. The capacity I was getting was actually 1700 mAH.
You can see the current hit zero and the capacity is still around 3100 mAH. I did a 1% to 99% uninterrupted charge in EUI. It would have been nice if the battery was actually 4100 mAH, but it does not appear that is the case.

Feelsbad, well its better than 1700 anyways, thanks for sharing
Hi bro, i heard from a guy that has recently replaced the battery to this HSABAT one that all OREO & Nougat roms are capped at 3100mah and you need to use another rom (this: https://t.me/LeitaEUI6) to get the full capacity of the battery, he says its real battery capacity its around 3800~ mah, will be cool if you try this rom and share results

Hey,
fist, thanks for that great guide!
I also changed my battery, but the capacity is only 3000 mAh. It is better than the old battery, but not 4100 mAh. I did the thing with the xml file. But nothing changed. I have lineageos pie.
I think there are more mechanisms which will decrease the capacity.
I think it will be the battery_cycles. If the cycles are high, the batteryvoltage will be cut. If I charge, the battery isn't at 4.4 volts.
I found this files to change the cycles and the capacity. But it is just temporary:
/sys/Classic/power-supply/battery/
If I write in these files, at the next start it will be changed...
Is there any solution for the shutoff voltage and charge voltage?
Thanks.
Excellent work!
This phone is mercifully reparable once the screen is off. My advice to people is to take that part very carefully and deliberately, it's about the only thing you'll break if you're careless. Once it's off, things become much easier.
Publishing information like this is very helpful to those who would attempt repairs of a solid phone, and it's a gift to the community.
Did someone remove the screen without breaking it? Maybe with a small peace of plastic sheet instead metal prying tool .

Those few dead pixels were the only damage to my screen, and it's damage I could have lived with. After this experience, I probably could have removed the screen without damage. This was the first smartphone with this design that I've ever opened.
I think this YT video shows someone removing a Le 2 screen without breaking it. https://www.youtube.com/watch?v=f_LExkf89z0 Be warned the fingernail thing you'll see grosses me out.
That said, there are numerous comments on XDA about people breaking their screen while attempting to replace their battery. It's highly recommended that you buy a replacement screen, especially if the lead (shipping + order) time is long for your country.
Thanks

Important extra info on the repair!!!
I've changed countless screens on this (and other) phones, and there is something VERY important missing on this tutorial (very well done apart from what I'm about to explain).
In the attach photos, (the same as in the OP post) you can see on the glue band (or whatever is called) a wider zone close to the motherboard. That is because you are supposed to grab that and pull straight. Then the glue comes off and the battery pops off nicely without being bend and with 0 danger. For this procedure you need to take out the motherboard entirely, which is pretty easy and quick. Take out the SIM tray (I always forget about this one ), disconnect the few connectors (vol and power buttons, fingerprint, USB Dock and the coaxial cable on the right), then 2 screws and its just comes out. After this the end of the glue band is clearly visible and easy to take and pull. Also, and this applies to all phones, you can use isopropyl 99% to weaken the glue (also useful for cleaning PCBs and fix water damage). Another note: you should always avoid bending a Lithium battery like in the photos, heat it to 70 degrees Celsius to weaken the glue and take it out as straight as possible.
Just as a note, I'm just trying to help here, not criticising other people's very appreciated apportions, just complementing them when I can.
Note 2: FOR LE ECO LE 2 USERS: The battery is mounted exactly like the Max 2, BUT you need to take out the USB PCB and speaker on the lower part of the phone instead of the motherboard, given that there is where the "puller" is. Why is it different to the Max 2 if the rest of the phone is identical? No idea... Maybe a brainfart?

I just replaced the battery and screen on my LeEco Le Max 2, and this post will detail the process. Hopefully it will be helpful for someone who is considering to replace their screen and/or battery.
Consider buying an extra screen
There are a number of people who have reported breaking their screen as a result of replacing the battery. I highly recommend that you buy a replacement screen if you intend to replace the battery. Unfortunately while removing my screen I also created a few dead pixels (which you'll see later). With all that being said, it is definitely possible to remove your screen without damaging it. I suspect that next time I will be able to remove the screen without damaging it.
Tools required
- small philips screwdriver (from Jeweler's kit)
- thin prying tools
- suction cup that tightly grips screen (you'll see the one I used later)
- heat gun or hair dryer
Onto the replacement procedure
Before you begin, make sure that you have plenty of time to commit to the replacement. It took me about 2 hours to swap the battery and screen. You should also read this full post before attempting to remove your battery.
Remove any sim cards in your phone and turn your phone off.
You'll need to heat up the perimeter of the screen on your phone. This can be done using a heat gun, however I manged this using a hair dryer. I spent about 10 minutes heating up the screen before attempting to remove the screen. Note that as you're removing the screen you may need reheat certain areas of the screen to loosen up the adhesive that secures the screen.
Next you'll want to apply the suction cup towards the bottom of the screen. Ensure that you have a solid grip on the screen.
I pulled the suction cup away from the screen, and began to notice that the sides of the screen were begging to come undone. I used a prying tool to sliced the adhesive that was holding the screen in place.
Go around the edge of the screen very carefully until the entire screen is removed. Remember the screen is glass and will break if it's flexed too much. My advice would be to go slow and use a lot of heat.
You'll need to remove two small screws behind the screen in order to disconnect the cable which connects the screen to the body of the phone.
Then disconnect the screen ribbon from the phone.
There will be an additional 15 screws which you'll need to remove in order to get to the battery. If you are just replacing the screen you can skip ahead to the section where I connect the new screen to the phone.
With all of the screws removed, you can pry the shield away from the back of the phone. You'll need to be careful, as a ribbon is glued to the back of the shield.
You can see the glue locations for the ribbon on the back of the shield. With the shield removed, you can now finally access the old battery.
Disconnect the ribbon that is right above the battery. Near this large ribbon will be another smaller ribbon that connects the battery to your phone. Disconnect the battery from the phone.
Now you can begin to remove the battery.
Important note from an XDA user
Be very careful not to puncture the battery as you remove the battery. The battery is glued into the base of the phone. You can see the two major glue strips in the following picture.
Place and secure the replacement battery.
Reassemble your phone. Before you put the new screen on, I recommend testing the original screen to see if you damaged the screen during the process.
You can see a few new dead pixels on my original screen. This happened as I was prying the screen open, so you'll want to be very careful as you remove the screen. Do not stick your prying tool too far in or against the screen. This damage is something I could live with, however since I have a new screen I'll go ahead and put it on. Turn your phone off before attaching a different screen.
You'll want to connect and test the new screen before proceeding.
Hopefully your new screen is working. Turn your phone off again. Now you should do your best to remove the old adhesive that was used to secure the old screen to the phone. However, you should only do this if you have new adhesive to secure the screen in place!
Your new screen should come with an adhesive template. Remove the outer edge of this template which will be placed on your phone's body.
Now place the adhesive template onto the body of the phone. You'll have to push down such that the adhesive has been firmly placed. Remove the template such that only the adhesive around the perimeter of your phone remains.
Connect the new screen's ribbon to the phone, and secure with the two screws. You can now firmly place the new screen into the phone. You'll want to firmly press the screen into place around the edges.
You'll want to keep pressure on the screen while the adhesive sets in place. I used a few pennies placed on the floor to give clearance to the rear camera. Then I placed the phone on the pennies, and heated up the screen again. I believe the adhesive will cure faster and stronger onces it's been warmed up.
I then placed a textbook onto the screen with a 10 pound weight, where I let the phone sit for an hour or so.
Enjoy your newly replaced battery/screen and hopefully this has been helpful!
AccuBattery stats for the new battery
I'm now on the second charge of the battery, and I figured you may be interested in some of the stats of the battery. You can see that despite the battery being labeled 4100 mAH, the estimated battery capacity is only about 3000 mAH.

Can I install 4100mAh battery to my le2? 3000 is not enough
Are you kidding ? You unnecessary quote an entire post asking a question you could have answered yourself just by reading the thread ? Unbelievable.
