[Q] Battery life and Android OS drain bug

For anyone using Android 4.0, specifically running it as stock on this device, do you experience the same battery drain issues commonly seen in Gingerbread? You know the one where the process Android OS uses an ungodly amount of battery life through suspend and events/0?

been playing around with the phone for the past 8 hours from a full charge, nothing unusual about the battery
tomorrow with normal usage after the full charge i'll get a better view about it

Does it take long to charge the battery? Like the nexus s. If its a slow charging phone like the nexus s then im not buying.

didn't think that fully charging it toke that much
i usually leave the phone charge when i go to sleep
removed from a 100% charge at 9:15am GMT

I own Nexus S too and experience the same, slow charging ... using the charger from Samsung (default).
So, I changed the charger and I use the one that came with the HTC Desire
And it is much faster, like 3 hours to go fully charged compared to more than 5 hours.
So, there you go, change your charger!

I can usually get my nexus S to a full charge in an hour or two, depending on how empty I let it get. It's fast enough that if I've forgot to charge & need to go out a 20 minute blast will get me through the evening.
No idea who made the charger.. I've got a house full of the damned things these days

So what about life time?

Just check your chargers mA output, the higher the nr, the faster the charge. A computer USB port outputs 500mA wich gives a rather slow charge normal mA on chargers is around 700mA -> 1A. Keep in mind though that higher mA resulting in a faster charge puts more stress on your battery and it WILL get hotter, to high numbers can even damage your battery so be carefull and monitor your batterys temp when trying a new charger!

Slightly off topic, but regarding charging...
Does charging via a "weaker" USB port damage the battery? For example, at work, the only USB port available is an old iMac keyboard USB port, and it's "weaker" in the sense that when I connect it to my phone, the computer tells me "A USB device needs more power.... "
I understand this might charge the battery slower, but does it cause any damage to it, short or long term?

As far as i know USB before 2.0 needed external power supply, meaning your device should not be able to charge from this type of USB. But to answer your question, no, you can not damage an electric device by undervoltage or lower Amps.

Hope to get the GN soon.
Like to see and test how the charging is with different chargers.
Have seen slow charging ( also better hold out ) with different chargers.
My best charging is stil with the original desire ( charges quick and battery holds longer ).
Galaxy S plus is slow, wildefire also slow...

Fast chargers

Hey people,
Before I went out and bought a car charger and second wall charger, I was wondering if you guys knew what the fastest ones were. I was using my friends car charger the other day and it literally did almost nothing for 20 minutes. The battery went up 1% every 15-20 minutes or so.

It's probably an issue with the cars 12v port, not the charger itself. No matter what your phone should charge around 3.7v. If you plug in a charger that has a higher output to try and speed charge it the phone and the battery have built in protection to keep it from charging above the recommended 3.7v. So just buy a reliable cellphone charger and don't fall for speedcharging gimmicks

I remember back when the iPad first came out there was a rumor that using an iPad charger to charge an iPhone would charge it faster, but the device only pulls what it needs (if it's designed well). I believe charging a device at a lower voltage may make it charge slower, but you can never speed it up unless the battery specifically possesses control circutry to do so. See http://en.wikipedia.org/wiki/Battery_charger#Fast.

10 hours to recharge phone ??????????

Can anyone tell me why it takes so long to recharge my phone ?
I use a charger cable from my computer (usb) to phone while at work --- then I also use it at home too.
Is it only the wall charger that does it fast ? not USB/laptop/computer ?
Last night it took me 10 hours (phone was on but I didn't touch it for 10 hours - internet/wifi/3g was OFF)
why does it take 10 hours ?
Is something wrong with the phone? battery? or is it the charger ?

USB only has a small amount of current that goes through it. Enough to power small USB devices and no more. I believe it's around 500mAH. But your phone is always drawing power, so the excess is what actually charges your battery. Your wall charger is 1000mAH which means there is plenty of current to charge your battery even with heavy usage.
Tl;dr: USB is weak and 10hrs is normal. Wall charger is much more powerful and faster.

damn thanks for the great reply.
Further more, I was at my friends house once, and he has a black berry (same charger as my SGS3) and he passed me this cord to charge and it honestly charged the entire phone from 5% to 90% in like less than an hour...
not sure wtf this was but is it possible ? is it bad for the phone ? for the battery ?

10 hours is not normal. And the average wall charger that comes with your phone is 750mAH, not 1000. The 1000mAH chargers are quick charge ones.
The fact that the blackberry charger worked well on your S3 tells me that you should get a new charger.

where does one find one of the quick chargers to buy ? (1000mAH)

you can find all sorts of chargers on amazon. you can find inexpensive ones at walmart too. i would recommend buying a samsung charger for your samsung phone. hold onto the one that came with your S3, even if it takes forever to charge. just use it to connect to your pc for file transferring, odin, etc.

Even though charging quickly seems good but if you can afford the time then use the one you already have z charging too quickly affects your battery health negatively , a slow charger will make sure your battery stays healthy for a long time , mind it by slow I mean a 750 mAH one not a faulty one in case yours is faulty .

The S3 charger is 1000mAH. I have two of them that came with my phones. And anytime I connect my phone to my computer I can leave it connected for hours and only charge a few percent. This phone just draws a lot of power.

thats interesting because i have 4 samsung chargers. 2 came with my old S2's and 2 came with my 2 S3's. the output on all 4 is 700mAH. i got robbed. of course, connected to a PC the output is max 500. even at that, i still get a better charge than a few percent when connected to a PC for hours.

Inconsistent Charge Rates using a variety of different cables and chargers.

I've had my Nexus 5x for a couple months now, I bought it through amazon refurbished. (My girlfriend has the same device, she bought hers brand new. Her's is the international model though) Here's a listing of the charging cables, and chargers that I have:
Anker Quick Charge 3.0 and USB Type-C 24W USB Wall Charger http://amzn.to/2mitz3n
Anker A to C 6ft cable http://amzn.to/2lbw2HW
Anker 24W Dual Port Charger http://amzn.to/2mx16Tt
(I bought the a to c cable to be able to connect to pcs or whatever, and the charger i had for my Nexus 5 and other micro usb devices.
Standard Google Charger https://store.google.com/product/usb_type_c_18w_power_adapter
Obviously the middle item there doesn't charge at full speed, it isn't intended to. But my charge rate using any of those devices is still over all over the place within each of those items specifications. So it isn't likely that is a cable or charger issue which is normally the issue when someone has charging rate problems. yes i know the charging rate slows down as it reaches higher percentages to prevent over charging and other types of battery damage.
My phone can be down to 20% battery when I plug it in and it could start charging at 110mA or 2000mA+. Whatever rate it is though, it isn't going to stay that way for very long. If it starts low, then it might work its way up into the 700-900s slowly or to around 1000mA. If it starts up high 2000mA it'll likely start working its way down slowly into the 1000-1800mA range.
Sure charging at slower rates helps the battery to last longer, but when i have no control over this, and at times it discharges faster than it is even charging it is bad. I can actually deplete battery sometimes, if its charging while video chatting. Albeit very very very slowly, but still. The battery life and range seems to be very good aside from this charging issue. The connection port on the phone seems really quite solid as well and wiggling the cord doesn't seem to affect the charge rate as best as I can tell.
My girlfriends 5x charges in about half the time that mine does, or sometimes its even worse, i just have to pay attention to what it is doing when i plug it in. So my question is, is this a battery problem or is there something else going on with the phone? What is it that throttles the charge rate down as the battery % gets higher? Is there a chance this could be faulty and causing it to be all over the place like this? Any ideas about this would be very helpful thanks in advance.
Ps: I really do love the device, it works great, I have no issues with it beyond the charging rates that can be all over the place. I can go from 10% battery to 75% sometimes in half an hour or so. Then i get times where it takes well over an hour for that much.
(I use ampere to measure the charge rates)

Charge rate goes down with higher battery temperatures. Let the device cool down a bit before plugging in, also keep the screen off to allow it to charge at full speed.
The charge will also slows down as it fills up, the last 10% will take the longest.

I appreciate you taking the time to respond, since you are the only one thus far. But as I said I'm aware of the charging slowing down for those reasons, and I've got another device to compare to. It isn't the same, and the device isn't hot.

There is no problem with your battery. The phone is badly designed. Unfinished SoC combined with a small battery and a big screen. Your money is better spent on something else.

He's not talking about battery life. He's talking about charging times.
Personally, no issues with charging here. Always goes 15% to ~90% in 60 minutes with the stock charger.

I don't have any issues with my battery discharge rate. For what it is, and what I use if for I'm happy with it. And from what I've read about the usages from others I think I have no issues there compared to others. I'm just referring to the charging rates, the way it charges

But due to an unfinished and rushed SoC, it doesn't charge faster. The charge rate of this device is limited to 40% of it's intended charge rate.

He says he already owns the device. No point in telling him how poor his purchase decision was. And it wasn't that poor of a decision considering how good it is. It stands up fairly well to my abuse and the small screen is OK to grip.
OK, a serious question:
1. Charging speed is affected by Charger (the thing that plugs into the wall), the Cable (how long or thick it is), and the Battery (how hot, how full it is). This is the basic, moving on.
2. Sometimes the C port is buggy and doesn't correctly detect the maximum amount that a cable+charger combo supports. Download Ampere or some other current measuring tool like GSam (although I never bother with GSam, Ampere is awesome), and make sure the max amperage is 3000 mAh. Anything lower than that means you have a low-powered charger, a less-than-optimal cable, or a hot or near-full battery. I recommend plugging it in at around 50% to make sure the near-full charge speed drop doesn't affect anything during your tests.
3. If that doesn't work, replace the battery. Final line advice.

He's already using Ampere to measure and has 3 chargers to compare with.

Is it possible to turn off the dash charge?

Hi,
Is it possible to turn off the dash charge? 5T is charged only overnight cause it can last the whole day anyway.
PS: I can turn off Fash Charge in my Samsung Note. So it saves battery if I charge only overnight and don't need fast charge feature.

There is no stock option for this. Maybe a custom kernel can support it or a custom kernel that doesn't support it at all would also be a possibility in theory.
I would suggest using a normal power adapter instead of the Dash charging one. Even a normal USB C cable prevents Dash charging as it can only be used with OnePlus' own cable. So maybe get a cheap USB C cable and use that?

Use a low amperage charger. Something like 1000mah. This will slowly charge your phone overnight. But make sure you use a quality charger.

Why would you want to do this? The OnePlus dash charger works differently from other chargers in that it holds the heat in the charging block. If you use a standard adapter you would transfer the heat to the phone while charging. I would NOT recommend doing this.

I use an Anker IQ 6-port Charger with a couple of fairly good quality cables.
I personally try to avoid any kind of fast charge because it will end up damaging the battery life faster than "standard" charge, even if the heat is absorbed by the DASH charger block. IQ Charge adapts itself with the needs of the device connected.
And my unit stays cool if I touch it while its charging.

Charge however you want. But for me, dash charger while getting ready in the morning or when you have a free half hour. Forget about charging overnight. I don't know your usage but for me, this works. The phone just sits on my nightstand without connecting overnight and I lose a very minimal battery amount.

It's fine at even less than 1 amp. We have two 5Ts in the house and charge them at night at 0.35 - 0.45 amp.

I saw the dash reduce Ampare when pass above 80%.
(When not rush I use official iPhone 1Amp charger.)

Use 5V/2A standard charger to standard usb type c.
Oneplus 5t = 5V/4A
Quick Charge = 9V/2A
Dash n QC have more power!

I'm using an old 1A Samsung power adapter and dash charge cable and in addition I also use Battery Charge Limit app to limit charging the battery to 80%.

No, it does not, especially not with dash charge. The excess heat is stored in the charger and is not transferred to the phone, and the heat is the only thing that degrades the battery faster.

Your informations are not correct.
Dash (or VOOC, which is the very same technology since OnePlus is an Oppo brand) uses high current fast charging instead of high voltage charging (QuickCharge 2.0/3.0 uses high voltage) and the circuit that produces heat in phones that are not Dash/VOOC compliant is inside the phone, while in Dash/VOOC is inside the charger.
Oppo and OnePlush themselves have acknowledged that it makes SAFE to use the phone while it is quickcharging, NOT that the battery is not getting damaged by the use of a fast charging method, even if it charges at a lower voltage and higher current.
The use of any fast charge technology implies to shorten out the overall battery life.

Just because they moved a bunch of the power regulation stuff to the charger doesn't mean the battery doesn't still get warmer. If you push 4 amps of current into it, it will heat up more so than when it receives, 1 amp.
Now you have me curious though, I guess I'll have to pay close attention to the battery temp next time I charge my battery. I've never used the dash charger, but perhaps I'll have to get it out of the box, and test with it as well just to see what kind of temps I see with a more powerful charger as well. I'm curious to see how much temperature difference there is.
I know on my Nexus 5X my phone always lasted long on a single charge when slow charged (0.35 amps), vs using the factory 3 amp charger.

Constantly topping up the battery overnight for 5-6 hours (assuming your slow charger will charge it to 100% in 2-3 hours) is worse than using Dash to charge it quickly in bursts in the morning and night when you have a spare 30 minutes.
I would never leave a phone stuck on a charger overnight. Especially since even the slowest charger in the works will charge the phone to 100% in three hours or so.

How does it imply that? Heat is the only factor. Phone is not getting hot(ter than slowly charging) when charging.

What is the truth? With the rapid charging the battery deteriorates faster or better a slower charging?
