Upon starting my day in the morning, I unplug my phone and start getting ready, when I come back I see the phone's at 90% already... that's odd. I've wiped the batterystats.bin file (has fixed issues on previous phones after a rom/root change) which fixed the issue for one day but day 2 it started again. I have root, twrp, and a few xposed modules running. Love the phone, battery life is sufficient regardless.
Any ideas?
here are some screenshots:
I have noticed that too. Take a look at your battery graph - does it have a big dip at the beginning and then level off like mine does?
I have noticed 100 down to 90 is fast, but after that, it is all good. Opposite of LG G2, which would stay at 100 forever and then drop down.
Anyway, battery life is great on the R1 HD.
Anyone have a guess what would cause this? It's odd, I've noticed temperature hops as well, not a problem, just means the sensors are budget ones, for example it'll go from 20 degrees C -> 20.5 -> 21, rather than 20.1 -> 20.2 -> 20.3 etc.
I don't own this phone but I can tell you this is common of rechargeable batteries and very commonplace with ANY Android phone. What happens is the phone charges to 90%, afterwards it charges much slower until it hits about %100 (this is to prevent the Lithium Ion battery from degrading or overcharging). Once it's at %100 the charging circuit will turn off and on while the battery percentage fluctuates between 90 and 100. This is just how batteries work as there is no way easy way to stay at %100 and stay plugged in without overcharging the battery. The confusing part is that Android will report that the battery is at %100 the entire time it is plugged in, so that when you unplug your phone you may be unplugging it when it's actually at say, %92. That's when you'll notice a rapid or sudden drop from %100 as Android adjusts accordingly.

That sounds like the problem. It makes sense, I've just never noticed it on any other phone I've had. This is a budget styled phone after all, can't beat that price for a great little device like this.
I have this exact same problem. I notice it's not as bad when I use the stock charger and charge using a wall outlet.

I do have this phone, experienced the same problem, and independently came to this same conclusion. To add, after waking up, I will typically unplug my phone, then plug it back in while I get ready. Afterwords, the charge "sticks" at %100. This seems consistent with the idea that the phone is actually at %90 when I wake up. Plus, the good news is that it can still charge the remaining %10 despite falsely showing a full charge.

Hi.
Anyone with the circuit diagram of the blu R1?
I have an audio issue in the motherboard and my friend needs that to fix it
Thanks

Wrong place to ask dude. Go to the q&a thread
Related
( meaning how many months before the battery loses storage capability, as opposed to "battery life" - how many hours until you run out of juice )
There are a lot of battery/charger threads, and some bright person actually looked up the TI charger circuit documentation, but I don't see anyone who has looked up what a li-ion battery needs to have a long lifetime.
So, I found information at:
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
Interesting tidbits:
- Charging to 100% means that you can use the device longer the next day, but is not necessarily best for the battery itself. Frequent partial charges are just fine, and are actually better for the battery.
- It seems to be particularly important for Li-ion battery charging to be turned off when you get to 100%. The LED turning green in the NC cable shows that the system is taking care of this (so you can safely charge overnight without damaging the battery).
Connecting the NC to another system that does not stop applying current at 100% charged seems to definitely be a bad idea. So, don't use any system overnight, that the NC does not recognize as "charging".
This indicates that charging from a laptop USB may "work" but may be bad long-term for the battery. Here it depends on whether the TI charging circuit is sophisticated enough to adapt to the non-standard condition. Since the charging indicators do not indicate "charging" then the answer may be "no", and while you are getting the battery charged up, it may not be in the best way. (This seems to be an area for more research about the actual NC charging system.)
- The critical part is to not use a USB cable or other charging system that is not recognized by the NC, when the NC is close to 100% charge, to make sure that it doesn't overcharge the battery. As the article states:
Li-ion cannot absorb overcharge, and when fully charged the charge current must be cut off. A continuous trickle charge would cause plating of metallic lithium, and this could compromise safety. To minimize stress, keep the lithium-ion battery at the 4.20V/cell peak voltage as short a time as possible.

- So, in summary, I think that a different brand of charger is okay as long as the NC recognizes it as "charging", and one should avoid charging in situations where you are "fooling" the NC by charging the battery when the NC is not noticing.
I honestly had no clue about this lol, thanks!
This might save a lot of headaches with "bad batteries" in the long run.
Thanks for this! Very interesting.
Well said, ADude. I'm so used to having to go onto forums and set people straight on the "myth's" of battery charging, but you hit it right on. The most important thing to remember is that overcharging drains your battery life (but most modern tech has auto off, in which it goes into a low power mode that allows for a stable current to just keep it around 99%), there is no benefit to letting your nook (or any other device) die completely before charging again, as there is not benefit to charging fully (or not charging fully) in the long run.
Thanks again!
LiIon likes being charged early and often... Don't run it down to 20-30% every time, it'll only shorten the overall battery. If it's down to 40-50% at the end of the night, put it on the charger.
Mine lasts 3 or so days before it gets near 40%.
Guys.
Am on ICS THS B16 with ICY GLITCH 14 B5 kernel..
I found this few mins back on my Cappy..
I had around 30% charge in my cappy and when i plugged in, i felt the warm on the back door while its charging.. It took around 1 1/2 hrs to Reach 80%..
Now When the device showed 90%, the back door is so chill cos of my climate here.. but still its charging...
Is it Normal?
Or The Charging thingi stopped in the OS and showing fake %???
What's the issue exactly? It's normal for a phone to get hot while charging
Sent from my CM9 ICS i897 Captivate
The issue is that.
As you said The device gets hotter while in charger...
But here it does not when its at 90% and it does till 89%
Oh wait, I think I read this somewhere. I vaguely remember reading that the battery will fast-charge until it reaches a certain threshold (like 80% or possibly 90%?), where it begins to trickle charge so it doesn't overcharge or something. I could be completely wrong; I might be referencing something completely different but maybe it's somehow relevant. Either way, I really wouldn't worry about your charging temperature unless it's getting really, REALLY hot.
Is this when using an outlet to charge the phone or a usb port on your computer? I've noticed different charge speed between the two.
I've also capped my charging at 90% because I've heard that charging to 100% isn't great for long-term battery life.

This is the exact reason. Li-Ion batteries can be damaged by keeping them at 100% charge or letting them get down to nearly 0% charge, so when batteries get to 90% they'll trickle charge. This is a normal safety procedure and all phones do it in some way or another - some phones will charge to 100% and then discharge slightly to hold at 90-95%
This is also why you should:
1. NEVER EVER let your battery go down to 0%
2. NEVER EVER use the charge to 100% - unplug, re-calibrate cycle to bypass this safety system that people post on here on a semi regular basis.

I have noticed that when the N6 is on charge, once it reaches 100% and left on charger, the battery starts discharging approx 1% every hour.
I only noticed this when my alarm was going off and when looked at battery usage it was saying 94% but nothing using it - installed GSAM and noticed that once fully charged it starts discharging even while on charge. If I remove charger and re-insert it starts charging again as normal.
Has anyone else noticed this issue. I have contacted Motorola to see what they say, but they are none the wiser and just think it may be a feature of the device/charger but not sure and said to test with another charger.

Not sure, I don't use stock or the stock charger. I would have thought the stock charger trickle charged. I remember my HTC desire used to charge to 100%, discharge to 90 and then charge to 100% in a loop as it didn't trickle charge.
Make sure your using a cable that supports data as well. My stock 5.01 and stock charger/cable does trickle charge.
It's perfectly normal to see this in such devices, though if it were going any lower I'd investigate further.
Maintaining a constant flow to the battery would burn it out so the charge gets it to full and then cuts out, allowing a little discharging and cooling of the battery. Once it gets to certain point, it'll start to juice the battery again.
Sent from my Nexus 6
thanks for the replies - I've not seen it drop below 90%, but I know if remove the charger and plug back in, it will start charging as normal - another thing I have recently noticed is that when you do plug charger in, initially it switches between battery/charger a few times and then starts properly charging - I wonder if this is feature of the phone or lollipop causing this. - other than this phone seems to work fine and have had over 2 days on a full charge
Well got it to drop to 80% while plugged in and it didn't start charging again until pulled cable and put back in
what charger are you using? i leave my n6 on a charger for hours after it hits 100%, and it never ever drops. id even say that when it hits 100% it doesnt stop charging. it keeps charging, with a much less inflow of charge than normal, but its still charging. for about 30min before it stops charging. then it just stays at 100%. sometimes i have it plugged in for 8-10 hours after, never once did it go to 99%. this is while using stock, and custom roms.

The new gen chargers actually cut the power when the battery Actually hits 99% and show it as 100% and stop it charging. But when the 100% drop to 99% (which is not actually visible), it automatically starts charging. But discharging the battery more than 1% is not actually a Normal thing, I should say. I also do charge over-night, never evidenced such thing. I'll suggest you to try with different turbo charger if you have one.
I'm using the stock charger got with the phone. I did contact Motorola over this and they were useless. I know charger works as charges to 100%. But it then just stops.
I have performed a factory reset to see how it goes tonight.
If still no good will speak with CPW and see what they say as don't fancy having to send off based on some of the forum posts
I have no issues with my N4 which has been connected to a power source for days and still shows 100%
I have also noticed that on the N6 when powered off and charge it doesn't show that it is charging
taken it into CPW and they have sent it off for repair - been told 16 days - at least with apple it's near enough same day, shame can't do same with android phones
I had called Motorola uk support and was promised email confirmation of call and also call back this morning regarding the phone and have had neither
back to my Nexus 4 for time being, just hope my Nexus 6 don't come back with any scratches, etc
I use a Qi charger, and notice this exact thing. Charge until it claims to be full, then stop altogether. So I set it on the pad when I go to bed, and wake up to it not charging and being down to around 95%. I was thinking that it was a characteristic of Qi, but when we got another (identical) Qi pad for the wife's Hammerhead, it "appears" to remain in charging mode indefinitely. Our Qi pads have a blinking white light when they are "charging".
what happens if you just plug the charger directly to the phone so not using the wireless Qi charger, do you get the same fault

Hammerhead does act differently to the shamu. I have both and used them both on the same qi.
Hammerhead trickle charges. Charging icon remains until picked up off charger.
Shamu stops at 100%, charging icon disappears. However, when I remove my Shamu, its always 100% or 99%.. Its never lower.

Good question. But judging by the rest of this thread, I suspect that it will behave the same with a wire as with the Qi. I don't ever actually use the wire to charge, since the ballistic maxx case makes access to the USB plug inconvenient.

I wonder if that could be a coincidence....? I.e., either you aren't leaving it on long enough for the percent to drop lower than that, or leaving it on long enough that it initiates a top-up just before you disconnect it.
Ok, so looking at the DT for the device....
https://android.googlesource.com/ke...ot/dts/apq8084-shamu/apq8084-moto-common.dtsi
Look at lines ranging from 823 to 854 for the smb1357 block.
Note low-voltage-uv = 2750000, max-voltage-uv = 4350000
In mv, that would be 2750 and 4350 respectively. That makes for a range of 1600 mV.
The recharge-thresh-mv = 200
Assuming a *relatively* linear voltage/percentage curve, 200/1600 * 100 = 12.5%. It won't be quite that linear, but this is adequate to give a rough idea of the charge cycle breadth in percentage points.
recharge-thresh-mv accepts values of 50, 100, 200, or 300. The smaller the value is, the tighter the recharge threshold becomes. At 50, we would be looking at roughly 3%.
So my conclusion: working as intended.
There is another aspect that becomes involved when using Qi, which is the bq51021. This one has a parameter "resume-vbatt-mv" set to a value of 4270 mV. That is 80 mV below full, or roughly 5%. Judging by only the name of the parameter, it sounds like it sets a Qi charge cycle breadth of 5%, but I don't understand the relationship between the bq51021 and the smb1357. I suspect that the two have to agree for Qi charging to work.

I don't think so. I put it on the charger at pretty much the same time and take it off at pretty much the same time but starting from different % remaining every day... If it did drop to 90%, i would have caught it at least once by now.
update: whatever you do if you are uk customer and purchased via CPW do not take it back to them - i found out today that they are not accredited repairers and they should have advised me it needed to go to Motorola - now trying to find out what is happening with my phone and when to get it back
I'm still trying to understand how my Nexus 6 works with Qi charging, and the results are a bit inconsistent.
I'm using an LG WCD-100 stand and a BlackBerry Blade charger, both of which are reported to work well with the Nexus 6 (in portrait).
I've had my Nexus 6 on the dock on my desk in work this week, and have been keeping an eye on it. I have the screen on all the time (so I can keep an eye on incoming personal emails). Most of the time the N6 charges to 100%. It then stops charging until it get to about 98%, at which time it starts charging again. So far so good. HOWEVER, on a few occasions it did not start to recharge (even with the battery down to the 70's), and I had to remove it from the charger for a few moments and then put it back before it would start charging again.
I'll try again next week (I'm only desk-bound Tue/Wed/Thu) with a different Qi charger, just in case there's a problem with the one I'm using (though I doubt it).
In the meantime, has anybody seen similar behaviour - or is it time to talk to Motorola UK Support?
the charging issue with it not starting again is the same as what i'm having on wired connection - if you install something like gsam battery monitor you can see that it is discharging while actually charging
I also have the LG WCD-100 (from when I had the LG G3) but not actually using it as I think first time tried you have to get it in the correct area for it to charge
I had problems with my Nokia charger. Because this phone is big and the back of the Nokia was less than half way up the back of the phone, the weight of the too of the phone pushed the bottom of the phone away from the charger.. Imagine the phone as a see saw and the top of the back of the charger as the pivot point. Also the unflat back didn't help
Limiting the battery charge to a fraction (70%-80%) of it's full capacity is a well known way to greatly extend the battery's charge capacity lifetime. There are several (root) apps created to automate this, that stop the phone from charging once a selected charge level is reached. Battery Charge Limit is one (https://forum.xda-developers.com/android/apps-games/root-battery-charge-limit-t3557002), ACCA is another (https://github.com/MatteCarra/AccA/). So far I have not been successful getting either of those to work with the ROG2. I was wondering if anybody has had any success with those apps or any other way to limit the battery charge on the ROG2?
The Rog phone 2 has its own function that lets you automatically stop charging.
But keep in mind this function is only useful if you are planing to keep the phone connected to a charger 24/7 then it's useful. Otherwise it's worthless if you disconnect your phone once it's 100% charged.
Battery also needs to discharge and recharge to keep it's capacity and function going. If you don't do this it can wear the battery out even if you stop charging at 70-80%.

Most of what you said is wrong.
The ASUS Power Master Battery Care feature slows and delays the charging but still charges to 100%. The feature is only useful if you have a regular charge schedule (which I don't, and DO mostly leave the phone on the charger) and even then, it's still charging to 100%. Repeatably charging a LiPo battery to 100% WILL decrease it's capacity significantly faster than if only partially charged. All phones already slow charging at high charge levels. There is no advantage to discharging the battery.

Did you ever know that even authority can be wrong in facts as well? I can confirm that battery feels alot better with discharge and charge than what it is with 100% all time or 70-80%.
How I can confirm is that I have a Microsoft surface Pro 4 and when I kept it on charger at 100% for a day or two the wear level jumped from 0% to 3% but when I discharged it and recharged it after some time then tear level on battery went back to 0% and capacity was back to its full capacity again. So discharge and recharge does not always wear the battery out. It actually makes battery feel better too.
So please don't always believe what internet and what authority States. Since on internet there is alot of false facts and authority gives alot of nonsense facts alot of times too.
Is it really wise to basically degrade your battery by 20% out of the box just so you can have 95% in 2 years? If anything, heat is the greatest factor for degradation. If you're that worried, just use a 2 Amp charger.

Yes, heat is a factor, but keeping the battery at 100% will degrade the battery faster regardless. If you simply do not need the additional 20% than there is no advantage to charging to 100%. My usage scenario is that the phone is plugged in a lot of the time and I very rarely need the full battery capacity. I've had several phone batteries bloat up under this scenario (and not using any fast charging).
When batteries degrade they don't stop at 80%. They generally keep degrading fairly rapidly. And you don't just lose capacity, as the battery degrades the internal resistance increases, which results in throttling and/or crashing.
BTW on some phones, ACCA will stop charging the battery when it reaches the desired charge level and run the phone entirely from external power.

Agreed. If manufacturers still offered replaceable batteries in their flagships, this would be somewhat of a moot point. When dealing with a sealed battery that is expensive and time consuming to replace, it's wise to do everything reasonable to protect the overall lifespan of it.
As for keeping it charged at 100%, I did that once and killed a battery in about 6 months. Not doing that one again.
Guys, it's so nice you are debating over the battery charging metaphysics but it does not help us solve the issue: our rooted phone can not be charged in a smart way using magisk+acc, ACCA or Battery Charge Limit.
Any ideas?

5. I'm facing this problem from the yesterday
6. Double plus sign on battery icon as well as fast charging text on home screen is also not showing while charging
What is the issue please help anyone
Submit a bug report to acca and maybe at least someone starts caring for the ROG Phone. The reason why it doesnt work is simply because ASUS does its own stupid thing while charging (thats what happens when 100 OEMs cook their own soup, a mess).
About the battery health:
A battery keeps its best health when its charged between 25-75%, is kept below 30°C and charged as slow as possible. Thats why its wise to stop charging at 80% with a slow charger, especially when you have a big battery anyway that lasts for a day with 80% charge.

There is no programmatic way to internally control the charging process without root, however there are some (not as good) alternatives.
First there is an app Accubattery that will give you a notification when the battery reaches a given level, you have to then disconnect the charger manually.
A second way to do this would be to use a smart plug and control it with Tasker. Don't know if anyone has done this but it should be possible.
Another possibility that is not vailable yet would be a kickstarter project called BatteryPal. This is a charging cable that had a bluetooth interface built in to it that would control charging using an app on the phone.They arr saying it will be available March 2020, but who knows.
I'm facing the same situation here. I'm next to a charger most of the time, so I like to use slow charging and not going above 80%. I was used to have battery charge limit installed in all my devices, but found this is not working with the rog phone.
My rog Phone 2 global edition over heats while charging
has anyone found a way even with root? I've tried ACC and some other app but they all done work.
I've also just tried ACC and Battery Charge Limit, but neither worked. It looks like there is something that keeps overwriting the charge control file all the time and allows the battery to charge anyway. Battery Care was disabled while doing this.
I am rooted, so I am able to test any potential solution.
Someone posted on r/rogphone2 a solution for this:

I've just tested it and it works for me.
Does anyone know of a legit charging adapter that isnt fastcharge and doesnt damage the phone or gets damaged itself after a while? I want to charge my phone without fastcharge but cant find a good charger
My old htc m8 charger got damaged after just a few times of using! Seems like the phone drained it dry
While at work, I leave my phone plugged in and charged at all times.
I don't have exact temperatures but I've noticed that it is warm the whole time. Anyone else notice this?

Are you using the official charger?
Some aftermarket USB C cables can damage your phone or even fry it completely.
If you are using a standard charger, I'm more inclined to say your phone is getting warm because the battery has been charging. If you have hotspot on, that can warm your phone up quite alot too... Basically the more your phone is doing the hotter it can get (Bluetooth/wifi/hotspot etc)
FYI: charging to 80/90% will make your battery last alot longer too, if you plan on keeping it a few years. Charging to 100% is the fastest way to degrade your li-ion battery.
If you are rooted you can limit your charge to 90% but depends if you don't have access to a charger all day you might need that 100%.
Hope that helps.

Yes, using the official charger. I also failed to mention that I have a case on my phone. Not sure if that is contributing to it.
Is it because charging to 100% counts as a full cycle? I will admit that I'm not up to snuff on battery tech and what the best way to preserve the battery long term. From my past understanding, if you take your battery all the way down and then charge it to 100%, then that was a full cycle. More cycles = degraded battery over time.
Not sure if this still holds true for li-ion batteries today.
Edit: My thought here is to leave it on the charger whenever I can, thus minimizing the cycles I put on the battery.

My suggestion is download accubattery, it will tell you your battery temperature and also it calculates the degredation and health of your battery. It will also explain how many cycles of wear you are adding to the phone.
Back in the old days with nickel cadimium batteries you needed to do the whole 0-100 thing, that was good for battery memory... But modern day lithium batteries actually are better being topped off and kept between 20-80% in an ideal world. So deep discharges and high % charges wear out your battery significantly faster... This is why electric cars often limit charge, by doing this they can extend the life of the battery cells quite dramatically.... but if you are upgrading yearly, don't worry about it.
Here is an article that will help you.
EDIT: try charging with and without the case and see if it gets hot, definitely cases can be an insulator. You can monitor temp in accubattery.

The idea that there is a set number of charging cycles for a particular battery, and every time you charge the phone you use up one of those cycles regardless of how much it charges (ie a 10% charge and a 100% charge both use one charging cycle) isn't how modern cell phone batteries work.
As noted, it is best to not charge your phone to 100%, nor do you want to discharge your battery to 0%. It is best to charge it more frequently for a smaller amount of charge each time as well. So charging a phone 10% ten times is better for the better than charging the battery once for 100%.
Heat is also a huge problem with batteries and the hotter a battery gets, the shorter life expectancy it will have. So definitely look into the issue.
If rooted, there are a couple of Magisk modules that control charging. They usually will automatically pause charging if the battery gets too high of a temp. Once a preset time has passed, it will restore charging again. The idea being that the pause in charging will allow the battery temps to drop. You can also limit the battery max charge to another value other than 100% if you want. 80% max charge is suppose to be the sweet spot for battery longevity, but anything less than 100% is going to add life to your battery.
Just so you know the phone does not charge to 100% or allow you to discharge the battery completely. Your phone just shows that you are at 100% when charged as much as allowed and discharged as much as allowed when you reach 0% charge. The partial charge thing no longer has much of any effect since the phone is doing it for you already but the internet hasn't' caught up to that yet. These chargers do stop charging at full and your phone should not be warm if it's charged but unused. So... are you using while on the charger? That's not a great idea because it's going to kick it into charge over and over. The fellow above was correct about using proper cables, I'm not sure that's much of a problem anymore but there still may be some ringers on Amazon and elsewhere. You could also have something discharging the battery enough to get it to charge continuously or close enough to it to warm the phone up over time, a wake lock can do it for example. Those can keep the phone on charge enough to warm it up.
In general with charging it's going to be best to keep your charging and total cycles down because capacity loss during charging is a real issue due to physical deterioration and transfer of materials in the battery caused during the charge. You would be better served by allowing it to discharge at least somewhat and only charging as needed rather than keeping it plugged in. Since you're at work it should be fairly easy to plan your charging so that you'll be able to get through the day without the constant charge. Not saying wait until it dies and then charge, that would be inconvenient, just that you would get more life if you reduced your charge cycles.
No matter what your phone is getting warm something needs to be addressed if it's doing so when not used but plugged in. The charger should stop for long periods and the phone should be cool after the charge completes.
