try acip I'm impressed with this rom. I have not noticed any bug so far.I I want to change the batteries because regardless of the Rom I have 3.30h SOT.I am counting on a new battery 6h Sot. I think it's real because on the original one sometimes I managed to achieve 5.20h SOT.But it was a year ago xd

Someone please test the authenticity of the battery capacity. Can be done by disabling fast charge so phone charges at static rate (5v1a or 5v2a) and time how long it takes from 0 to 100%

[LeEco Le Max 2 Questions & Answers] xlcashlx:
I just ordered. Will try to report back on the battery quality/specs.

Also I try to detail the replacement process.
[LeEco Le Max 2 Questions & Answers] LoBinS:
Hello everyone, a few weeks ago, I ordered the battery and indeed, it's written 4000mah (I'm not sure it's true, 3600mah is more real) and also a screen.

To take off the screen, it's really easy! You just have to warm it and to use a tool to pull off. You can find video on YouTube who explain everything ;)

At the moment I wanted to pull off the battery, I don't know what happened but it becomes really hot and a smoke came from the battery. But I could stop this, and take off the battery.

Then I put the new battery (same size) and look perfect, no problem with that

Put the new screen because I broke the LCD (not the glass, just the LCD. Our screen on Le Max 2 is so poor quality to be honest).

And after around 1 hour, I was good to go! Everything work perfectly, about the battery because everyone want to know! :laugh:

It changes a lot, I was the feeling to rediscover my phone after more than 1 year and a half. As I'm running on Los 15.1, the sot is low but I can say it's 2 or 3 times better than before with my dead battery. I can survive for a day now :fingers-crossed:

It costs me around 23$, and I recommand to all of you, you just have to take your time, to be careful with what you do and it should be OK :svetius:

[LeEco Le Max 2 Questions & Answers] TheLastCanadian:
It is very likely you punctured your old battery. Lithium reacts violently with oxygen - in future, for those unaware, make sure you keep some tape nearby to cover any damages done to the battery during installation, as again, letting it become exposed to oxygen is not a good idea.
[LeEco Le Max 2 Questions & Answers] AgustinH:
is there another place to buy batteries? besides aliexpress?
[LeEco Le Max 2 Questions & Answers] Immortal68:
Sorry for the mass quoting. Just wanted to make sure everyone who was interested notices this update.

I tried changing the battery and fingerprint sensor. I was really careful getting the screen off, heating it up evenly and not using too much force. There's quite a bit of sticky tape, especially at the top and the bottom and I took all the time to open it, but still...

- display broken (vertical stripes all over)

- two stuck screws right behind the display that won't budge - no matter what! I tried using a rubber band for traction, different screw drivers, heating the screws a bit, every advice I found on the interent - nothing works!

So, this is basically a cautionary post.

Don't just open up your phone to replace the battery: Have a replacement display in the back, because those things break so, so, so easily I'm honestly wondering if LeEco somehow rigged them to discourage people from opening up their phones.

Also, don't expect it to be worth it. In my case I spend about 15 bucks for battery, fp reader and tools and will have to spend another 20 or so for a display replacement and I got nothing out of it, because of two screws that just won't give. I'm seriously so frustrated right now.

I don't think this phone was meant to be opened. My next phone probably won't be LeEco. :(
[LeEco Le Max 2 Questions & Answers] LoBinS:
When I changed the battery, I didn't have any problem to open the phone, it was really easy in fact ? I thought it would be more complicated but it didn't

I can understand how frustrating you are but it happened only to you ? you always need good tools when you want to open Phone or stuff like that.. The battery cost me around 8$, and the screen 15$ so yeah it worth it..
[LeEco Le Max 2 Questions & Answers] Immortal68:
I thought opening it went fine as well - but the screen does seem to be very, very fragile. Of all guides I've read so far more people said their display broke even when they were being really careful than people who opened it up without damaging their display. That's why I'm saying, keep a replacement display nearby. Chances are you'll need it.

I was lucky enough that a local mobile repair shop I went to yesterday was able to loosen the two screws that gave me a headache. So now I'll at least not have broken my display for nothing and will be able to change battery and fp reader until the replacement screen arrives. :good:

edit: Did I understand you correctly in that you had to buy a screen replacement? So, your screen was already broken?
[LeEco Le Max 2 Questions & Answers] LoBinS:
Nope, my screen was working great but I was almost sure that opening my phone will break it. So I ordered a battery and a screen
[LeEco Le Max 2 Questions & Answers] Immortal68:
Ah, alright. Any guide you followed or anything you were really very careful about? I'm just wondering where I went wrong that my screen broke, but yours didn't.
[LeEco Le Max 2 Questions & Answers] LoBinS:
When I took off the screen, I broke it.

But I already knew that I'll have to change it

I make it warm, and slowly took off the glue. Nothing more ?
[LeEco Le Max 2 Questions & Answers] Immortal68:
I misunderstood you then. I thought you meant that you had no problem opening the phone without breaking the display. I managed to do that as well, but usually the display shouldn't break that easily. I haven't seen a guide yet where someone was able to remove the display without breaking *something* in the process. This seems like shoddy work on LeEco's part.
[LeEco Le Max 2 Questions & Answers] LoBinS:
The screen is really cheap, it does what it made for, nothing more, you have a 2k screen for less than 15$ :/
[LeEco Le Max 2 Questions & Answers] valy_cta:
Guys, sorry to interfere but I kind of doubt that any of you has a hot plate that heats up the screen to that specific temperature for the glue to get loose and that you've used the proper place/force to lift the screen enough not to shatter. Honestly, this is being done only in specialized repair shops and I don't get the point of complaining here about "fragile screen", etc... It has to be well understood that any repairs at home are done at your own risk. Nonetheless, the phone was not meant to have the battery replaced by its users, therefore, the phone doesn't have any screws, nor removable back.
[LeEco Le Max 2 Questions & Answers] davidanger:
So Waiting for your feedback! Good Luck!

By the way I just replace my Battery with new one last week by myself. If I see this before maybe I can try BN43 (Redmi Note 4X ) for you.

The SMB1351 (X820 Using Charging IC) 's maximal Quick Charging Current is 4500mA, If replace 4100mAH battery, It is about 1.1C Charging Current, So I think Quick Charge is not a problem. It should be support, the battery temp should not be increase too much, maybe more cooler than Official one.

Great idea ! ~:fingers-crossed:
[LeEco Le Max 2 Questions & Answers] typos1:
A hot plate?! No one in their right mind would use a hot plate, youre supposed to use a hot air gun and a suction tool to hold the glass ! The phone does have screws inside.
[LeEco Le Max 2 Questions & Answers] valy_cta:
I kind of understand that English is not our mother language, but you took it literally. A "hot plate" for cell phone dismantling is specifically designed for that purpose and you cannot heat up your soup on it. It's obvious that you have no idea what you're talking about. If I'm not wrong, it's supposed to heat up the glue at about 80-90°C, and then you can easily detach the screen from the body. At home you can't do that, it's either too hot, either too cold, and in any circumstances, it is wrong. I don't work for a repair shop, but I have friends who do, and removing the screen intact is not as easy as people think. Even repair shops break a lot of screens... And the thing with the screws is that there are a bunch inside, not outside (like the iPhone has 2 pcs, just unscrew them and you can replace the screen).

Another thing that users who remove their screens should take into consideration is the fact that the screen has to be fitted back. Solutions for our phone are double sided tape of which quality is doubtful. For Xperias there are specially made patterns, which in my opinion is a better solution as you can't make the corners properly with the straight tape.

Bottom line, at home it's not so easy to do a proper repair without breaking the screen. Better purchase a new display in case you are planning to open up the phone for whatever reason.
[LeEco Le Max 2 Questions & Answers] typos1:
English IS my mother language.

No one use a hot plate - professionals use a hot air gun to remove screens - there should be no contact with the glass.

I know there are screws inside, that what I said !

I ve changed the screens on a severl phones with this type of construction.
[LeEco Le Max 2 Questions & Answers] valy_cta:
My bad regarding mother language, I'm using the app, so I haven't seen where you're from.

Regarding screen replacement, have a look at this one until minute 6:30. I know the glue on this S6 is spread across the entire screen, but below is the hot plate and the same process should apply to our LeMax2. I won't go into details and I think I'll end the conversation here :)

[LeEco Le Max 2 Questions & Answers] Immortal68:
I'm not complaining about the screen price. It's absolutely reasonable. I just don't think the screen should break that easily. I replaced parts in my Xiaomi Redmi Note 3 and had no problem with the screen then.

You can absolutely remove the screen without shattering it. I used a simple hair dryer to heat it up and lifted it very carefully from all points. There still seem to be some weak spots that somehow got damaged, so my screen broke. The stripes I got afterwards seem to suggest that it's rather the flex cable connecting the screen to the rest of the phone than the screen itself. Besides bending it a bit I didn't touch that.

I'm complaining because I did the same procedure with my Redmi Note 3 and the screen was fine. I think everyone is well aware that there are risks to opening up a mobile phone that wasn't quite designed with that in mind. Most mobile repair shops in Europe specialize in Apple, Samsung, Nokia and a few odd other companies here and there, but have no clue (and no parts) for china mobiles. That's at least my reason for opening it up myself (the other one being that these shops are often times ridiculously overpriced).

---

Update on my part: I managed to replace battery (3100mAH to 4100 mAh) and fingerprint scanner and was able to turn my device on w/o problems. Since I'm still waiting for my screen replacement to arrive I'll have to leave rigorous battery & fp testing for when it's here. SO far, I'm happy with how it works though.

Anyone wondering how to do the whole thing I'd recommend using this fp replacement guide. In "Part 3: Removing the Metal Back Plate" I had to remove two more screws right on top left/right though which are not marked in the guide. Also, the Back Plate is glued to the red connector (see Part 4), so you have at least some resistance when removing it. To remove the battery you have to pull the transparent stripes seen in the picture at "Part 5" upwards which will pull out the glue stripes holding the battery in place.

I'll post an update when my screen arrives and I can test battery and finger print reader.
[LeEco Le Max 2 Questions & Answers] typos1:
Never seen a hot plate used in any of the videos I ve seen about opening phones, thats the first.

It still seems a stupid idea, much better and safer to use a hot air gun.

Another update on my part. I replaced battery, fingerprint and (involuntarily) screen. So far I haven't noticed any difference in battery life and the terminal command shows quite a bad result, considering that I ordered a 3600mAh battery and the one that came said it was 4100mAh on it.

I'm no my LineageOS Installation - the same one I had before battery change and the new battery bugs, in that it will only load to 94% max. Not sure if this screws up the results.

I monitored the new battery before with AccuBattery over about twenty full charges and even there it showed the capacity as only 3250mAh.

I'm quite disappointed. Fingerprint doesn't work any better either - again, it might be because I didn't reset to EUI.

First full charge on new battery. I'm running Lineage 15.1 (last builds before Treble). My original battery was showing Full charge: 1702000, so this appears to certainly be an upgrade. I don't know about SOT, but with my previous battery I was only getting 1.5 hrs max. Additionally when I pulled out the original battery, it appeared to show signs of physical wear judging by how the battery was physically flexible... For reference the phone is 1.5 years old. This entire year I only charged the battery using QC 3.0 quick charger, and I don't think I'm going to do that anymore.

I took pictures of the whole process, and will write up a post detailing the replacement when I get free time. I did not break my screen on the replacement, but did damage a few pixels in a couple spots. Good thing I had ordered a replacement screen as well.

[LeEco Le Max 2 Questions & Answers] xlcashlx:
New screen is indeed 2k. Colors seem okay. My only complaint so far is it appears that the auto / adaptive brightness doesn't work like it use to. Also the LED buttons on the bottom of the screen are way to bright. I think I've turned them down to something like 3%...

The battery was described as 3600mah and showed up as 4100 mah. Quite a few people have expressed doubts that the battery really is 4100 mah.

EDIT:

Does changing

<item name="battery.capacity">3100</item>

in power_profile.xml https://github.com/LineageOS/androi...works/base/core/res/res/xml/power_profile.xml change battery capacity? I might create a lineage build right now to find out...

EDIT2:

I changed the power_profile.xml capacity value to 4100 and compiled... It does not appear to change the estimated battery capacity at all. Details on how to do that I posted here: https://xdaforums.com/showpost.php?p=77657932&postcount=2
