[q] i'm battery murderer

So here's what happened:
I just got my hTC HD7, it had some juice alredy so I played around with it, when the battery got empty, I charged it. But my plug has a on/off switcher. I tripped over it and turned it off. This was the first time I charged the phone. What shall I do? I put the phone back in the box. Shall I get a new battery or charge the phone again? HHHEEELLLPPP!!!!

Just leave it to charge? Accidentally turning off the charger while the phone is charging doesn't do it any damage. I knock the plug loose all the time.

A full charge for the first time can be interruped without issue, lithium-ion batterys do not carry a charge memory unlike older handsets where you did have to give a full charge from the outset.
To get the best life from your battery or spares try to do the following:
Try to keep the handset out of any heated environment (eg; a car on a sunny day with windows closed) as this could stress the battery and decrease the charge life.
Do not use another charger that could stress the battery with over voltage (keeping it plugged in after full charge with the regular charger will not affect the battery) the battery will degrage however if it were allowed to exceed the 4.20V/cell limit.
If storing a spare battery for an extended period of time it is recommended that the charge level is around 40% for optimum lifespan.

first off, thanks for that helpful tip on saving batter power. i just have a question concerning the above mentioned (quote) do computer/laptop usb ports supply the same voltage as the charger that came along with the phone? will it hurt the stock battery if i always use the laptop usb port to charge my phone?
thanks in advance

the first one seems to be the same as the stock battery but the second will surely get you through a day without charging with all phone features on(data,wifi as in everything) or a whole day of heavy calling and sms. but if there are only a select features turned on or on stand by mode roughly it will last you two - two and a half.

Seriously, c´mon guys, if the battery dies, just replace it, charge the battery how you want (partial charge is better for Li-based batteries than a full charge), also, HD7 stops charging the battery once it reaches maximum charge level, so if you keep it on charger, green LED will be on, but no charging is done, this is to prevent stressing the cells (cells are most stressed when on full charge and fully discharged). So no worries here .

[Q] First charge, how to do it?

Much has been said about the best way to proceed with new battery technologies, but I would like to ask how you did things when you bought your OB and charged it for the first time. Did you consume the remaining ~30% left from factory before the first charge or did you charge it regardless what was left? when you did charged it, did you wait 8hrs or more to extend battery life in the future or just waited until it said it was full?
Thanks for your help

First charge: well, you grab the usb cable. One side, the small connector you connect it to the upper side of the phone. The big usb connector, you connect it to the AC-to-USB adapter. Then, you plug in to the wall this big piece. Just kidding
If you read, you will find the experts saying that Li-ion batteries don't have memory effect and you don't need to do a first charge or full charge-discharge cycles. God forbid that I contradict them, but my experience says that the best is doing cycles from around 0% (well, below 10% you can plug it in), to 100%. Never parcial charges (for example from 65% to 100%, or from 20% to 60%), although I lately do lots of parcial charges because I can't play anymore to run out of battery.
The first remaining 30% out of the box, well although I knew I "shouldn't" use it (maybe), I just do because on the way home after picking it up, well, I want to try it! It won't hurt. Use it and when it's at 10%, charge it completely, to 100% and hang on a while before unplugging.
EDIT: no need to wait 8 hours or anything. Just 100% and some more minutes. Charger will stop letting the electricity go once the phone has said "hey, I'm fully charged". It's a environmental and energy saving thing. Completely pointless waiting hours (it won't charge).

8 hours ? Nope
Just normal charge when the battery is completely depeleted (about 5% or less)
so it i'll be replaced with the new 'ion' or something,then the longer battery life you'll get
When battery is still full or half of it's capacity (more or less), it's not recommended to charge it
Let's take an example, a half burnt tree branch, what happen to the burnt one if you keep burning the branch? Ashes
That's what i think and do
Sent from my heart into yours

Thanks for your responses guys, I want to clear out all my doubts since I want to buy this cell phone, and hopefully I can find a good price soon

Does the OB original charger prevent overcharge?
I usually leave my OB connected to charging during the night. Is it ok?

Charging time limit

I've noticed that the phone can be fully charged in an hour. Is it bad for the battery to charge the Turbo all night like I used to with other phones?

I personally don't charge my phones through night, I prefer to fully charge them just after I arrive home and before I'm going to sleep, and my battery health in my last phones has been healthy and not decreasing the performance so quickly.
I think the whole point to get a Turbo charger is this, to be able to make the phone charge quickly and don't let them plug to the wall the whole night.

Charge Limiting to Extend Battery Life

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?

I'm facing issue with my Rog 2, my phone is not charging fast
1. I'm using 18w charger come with the phone to charge
2. I have used Xiaomi 2i power bank with 18w output to charge my phone (still not working)
3. I restart the phone on charging it goes down 36% to 29%
4. On charging when i restart the phone it goes 8% to 13%
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:
https://www.reddit.com/r/ROGphone2/comments/ev0put/hows_this_it_never_reaches_100/
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

Phone is hot while plugged in and @ 100%

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.
https://www.wired.co.uk/article/how-to-improve-battery-life-tips-myths-smartphones

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.
