Charging from PC - worth while?

Is charging our Kaisers from the PC ok? How much power does the USB provide to the Kaiser? Same as the standard adapter? I am asking this because I found no answer on the forum and I would prefer to load it directly from the PC every time rather than keep using the standard charger and putting it in the power outlet.

my advice for you to stop this option
because normaly we keep the phone connected to the pc for a long time and it makes the phone in charging mode all the time and iam sure that will make the battery dies fast
stop this option by disabling it from the battery options you can see it by clicking on the battery icon on the start bar
greetings

My phone has been plugged in to the USB at work all day, 5 days a week, for 5 months now. I can still get about 2 days out of the battery when I need to - for instance, after unplugging it each Friday at 5 I usually won't have to charge it until the same time on Sunday, the only time it generally does get plugged into the wall charger. I'm pretty sure my battery performance is still on a par with most people's - ie, not amazing, but quite livable with. It's certainly not showing any signs of harm from overcharging.

Same here.. no problems. I don't even know where my charger is.

I charge mine from the PC all day too, and it stops charging when its at 100%. The bottom line is this: a USB port delivers a minimum of 500ma at 5v, the wall charger is probably very close if not more than that. The charging circuit in the phone does all the work of converting the 5dc into a charging voltage/current required by the battery, usually ramping up and down. Theres no difference other than maximum current between a USB port and ANY 5vdc adapter.

Wall wart gives 5V/1A. USB at 5V/500mA will not harm your battery. If you're using the standard battery, USB charging is appropriate to keep it topped up.

Isn't the constant charging of the batter bad for it?
I mean you charge it use it for a while then hook it up again and so on, isnt it better for the battery if you wait until it says that you have to recharge it?

According to my BatteryStatus, my wall charger gives me around +500-600mA (depending on programs running) and USB 2.0 charging from the front port on my computer gives about +100-300mA (depending on what's plugged into the computer and program usage).

That was a nicad battery issue lithium batteries do not have that issue.
-McMex

i think the point here is not if you charge it by usb or charger
for many people as they said it goes as well ok but it's an old advice used to be known that it's not good for your battery health to be on the charger all the time
also the same fact that it's always better to let the battery goes empty before you recharge it again some people have the sickness of recharging batteries when it's just gets 5 percent less , then they immaditaly start to recharge it again and this is a big mistake because in the long period the first levels of the battery start to die because they have never been used

Actually, its quite the opposite of what you say. If you let Lithium batteries discharge all the way, they will loose their capacity faster.
The following link will back up my claim:
http://batteryuniversity.com/parttwo-34.htm
Relevant quote: "Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns."

usb v wall charger
My kaiser
wall charger charges battery from flat (1%) in 1 hour
USB on PC takes 4 hours to go from 15 to 80%, only over night did it get to 100%.
I use wall charger everyday now.

i use the pc option especially when i am traveling and only have my portable. When using my portable, i plug my phone in to get a charge... i like this option as it saves me from having to lug around another adaptor as well as being able to charge my phone just off the batteries of my portable at any time,,,, good option

posted twice --- as usual being a post hog

It's fine. It just takes longer to charge, especially if you're transferring a lot of data.

With the lithium ion chemistry, it is very detrimental to the battery if you let it run down to empty all the time. The batteries do not like this at all and will exhaust much quicker this way. If you were to store the batteries, you should store them at 40% in a cool place as that would only lose 2% of life per year I believe. At 100% storage, you can lost 20% a year of life. A little reading at that battery university website goes a long way

So what happens when your battery that you leave stored at 100% loses 20% a year and a few years later it hits 40%?

haam1978: You are surely right for NiMh. But I don't know about Li-Ion. Time will tell. For now, I prefer to do it your way: discharge almost completely, BUT NOT TO 0%. Mostly to 5 - 10%. But the problem is that my stupid Windows doesn't report the life of the battery accurately ::- (. I got a Mugen 3000 Mah batt...
rotohammer & johnny13oi: Interesting website indeed. Unfortunately as I told haam, I can't get an accurate battery reading for this huge battery I got. Anyway, I'm still reviewing it ::- D.

100% correct.
On a side note, my kaiser will get fully charged way faster when connected to the wall as opposed to USB. (always connected to a desktop with a real big UPS).

[Q] the phone is very hot when charging

I 've lost my original charge.so I have to use an Ipod charger to instead it.
But the phone seems very hot every time charging. What shoud I do now?
In additional, the battery drained so much. It took 4 minutes to lose 1% battery.I 'be bought the phone for 6 months,so why does it drain battery so bad?
Please help me and forgive for my bad in English.

2 options:
1) Your battery is fried.
2) Something is running on your phone that causes it to drain battery (forgot GPS app running in the background or something?), which is also the reason for heating up.

How can I know that my battery was fried? Example like how many mAh are there in my Batt?
I was looking for BatteryDetective (like in my friend 's iPhone 3GS) but it is no avalible for my device.
Also,how to check what was running in background? GPS is alway turns off when charging,certainly
I turned off the phone and charged.and it was still hot,but not much as when the phone turn on

In general, using a different charger won't damage your phone. Apple chargers are often capable of supplying more current than other chargers (for example, 2100mA rather than 1000mA), but the phone will only draw as much current as it needs. As long as the charger is supplying proper, in-spec voltage, you shouldn't see any difference. Your phone is probably getting hotter because it can draw more power from the iPod charger than your old charger, and can now charge the battery faster. I wouldn't worry about it unless the heat is causing problems. Cheap, off-brand chargers sometimes don't supply proper 5V, so don't buy crappy chargers.
Your battery discharge rate is a separate problem. You can check what's been using battery power in Settings|About Phone|Battery use. In my world, Display, Wi-Fi, Cell Standby, and Phone Idle are usually the top items. Checking the wear level of a regulated LiOn battery is kind of annoying; they're cheap enough I just replace them every year or so (500 cycles is a pretty good lifetime).

Thank you very much !
Are there any app like BatteryDetective for android? I 'd like to know how many mAh of my battery

[Q] Fun with fast charging in car

OK so I am running Trickdroid 9.1 with ElementalX kernel set to fast charging. I also have a specialist fast charging USB cable (no data). The car charger supposedly outputs 2.1 amps (at least one each port and I am only using one).
So basically before I found out about AC charge mode my battery was draining out when running NavFree app. Even when I changed to fast charge mode with an older (thin) USB data cable it was losing charge when running NavFree. Which is why I got the fast charge cable.
Now it seems to retain it's charge when running the app. At least it does not drain. However it never seems to charge either. It was on 78% charge and stayed like that throughout a 10 mile test journey. Using Battery Monitor Widget it shows that it never rose much over 600mA usage. But mostly used a lot less and sometimes dawdled around the trickle charge values.
Is there a reason why it won't charge up the battery whilst running an app like NavFree at the same time?

Yes power saver mode is on. thanks for the link I am reading through it. So far it seems the HTC sucks on car chargers (but doesn't draw enough or if it does causes battery overheating issues if in a warm climate or have heating on).

The best results for me have been making sure you are using AC charging and have power save mode on. If I use that method my phone charges but it's a slow process.

It will draw *up to* 1A, but only when mostly discharged. Try it with, say, 20% charge, you should get higher current.
Once the battery hits around 4.3V, charging changes from constant current to constant voltage; the current drops.

Which is a terrible algorithm when you want your phone charged to max when driving using satnav apps. I want my phone to get a full charge on a journey. Not be down to 78% or lower at the end of it. I may need the phone for the next couple of days without being able to charge it.

[Q] Info on battery stats

Greetings,
I just bought HTC one m7 from a friend. I have noticed that the battery is draining pretty fast and I am not doing any heavy usage. I installed GSam Battery app and I am constantly refreshing it without letting the screen sleep. Nothing else is running in the background. It shows 30%/hour drainage. Screen brightness is set to 50%. 3g network is connected and I have tethered the phone to laptop through wifi hotspot (just casual browsing im doing on my laptop).
Also the phone is charging pretty slow (compared to my previous lumia phone) which is annoying. If i connect the phone to laptop for USB charging, the battery goes down instead of charging.
Is there an issue with the battery, or is it just normal? Kindly enlighten me.
I will use the phone tomorrow with a 100% charging over night and can post the battery stat pictures if required.
Kind regards, Jasim

Charging the phone using a usb port from a computer will always result with extremely slow charge or even discharge if the phone is consuming more power then what it receive from the usb port.
The USB 1.x and 2.0 specifications provide a 5 V supply on a single wire to power connected USB devices.
A unit load is defined as 100 mA in USB 2.0, and 150 mA in USB 3.0. A device may draw a maximum of 5 unit loads (500 mA) from a port in USB 2.0; 6 (900 mA) in USB 3.0.

Wall charger can deliver more current and will charge the phone much faster. As for the battery drainage, it might be some app draining or even the battery might need to be replaced.
Lithium batteries do lost capacity over time.
Lithium-ion battery packs are expensive, so if you want to make yours to last longer, here are some things to keep in mind:
Lithium ion chemistry prefers partial discharge to deep discharge, so it's best to avoid taking the battery all the way down to zero. Since lithium-ion chemistry does not have a "memory", you do not harm the battery pack with a partial discharge. If the voltage of a lithium-ion cell drops below a certain level, it's ruined.
Lithium-ion batteries age. They only last two to three years, even if they are sitting on a shelf unused. So do not "avoid using" the battery with the thought that the battery pack will last five years. It won't. Also, if you are buying a new battery pack, you want to make sure it really is new. If it has been sitting on a shelf in the store for a year, it won't last very long. Manufacturing dates are important.
Avoid heat, which degrades the batteries.

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
