[TIP] battery swap without power down

I have a couple of spare batteries and tried a hot swap of battery without powering down while connected to a charger, and it worked to my surprise.
handy for charging spare batteries, or popping on a fully charged one if you're on the way out somewhere or even keeping open apps in a running state.
I guess this may be common knowledge for some people, I never tried before with my N1 as I am sure I had tried it on other phones and they did not stay booted.
If it makes any difference I am running Cyanogen 6.0 rc3.

Don't know if it's the same, but on the back of my laptop battery, it says being connected without a battery may cause damage to your system.
Not sure about that, but just sharing.

Think batteries offer an extra degree of filtering.

I have tried this before, it did not work for me. Phone shut off as soon as I took the battery out. Was connected to USB at the time.

Tried it with a car charger and it turned off lucky!!!

Appears not to work for everyone - I was using an HTC mains charger, maybe it has something to do with the type of charger or what ROM/kernel you are using?
As far as laptops are concerned, i am sure I read somewhere that it is beneficial not to have the battery connected if you use them on mains most of the time due to the heat degrading Li-Ion batteries over time, but I can see the point about the battery filtering and providing protection against spikes and brown outs

Your car charger probably only provides 450mAh then.

i wouldn't be surprised if it only worked with the htc charger plugged in. as long as the power is stable (aka won't dip in voltage when something high power like the vibrator turns on) then the phone will be fine. The phone knows if it's an htc charger, a computer usb power, or some 50c knock-off charger and it's understandable that it would protect itself by changing its behavior based on the power it can reliably draw.
macbooks, for example, will downclock their cpu when the battery is removed to make sure the silly little apple transformer can keep the voltage up.

Batteries provide voltage stabilization from wall power, so it's definitely safer to leave them in...but a few moments of wall-only power won't hurt. If you're really worried about it, hook up your charger to a power conditioner.

Works for me via USB but only when ADB is running... if I kill the ADB server the phone shuts down...

[Q] USB plugged in all day

Is it alright to have the SGT plugged into a USB port all day (approx 9hrs) ? I'd like to have it keep its charge (maybe even gain a little) while I'm at work so I can have a decent amount of juice for the trip home and until i go to bed. Or is this a good way of burning out my battery real quick? Thoughts?
Oh and as a side note on USB charging, I was able to get from 15% to 99% in 7hrs with the screen off the whole time.

Is it a slow-charging USB port? Or is it a powered hub? If I'm not mistaken, slow-charging a lithium-ion based battery pack is actually better for its life as opposed to rapid charging.

Its the regular port on the PC not even high speed usb so i guess it isn't powered.hmm guess the charging part is OK..but what about leaving it plugged all day even if the battery is at 100%?

All usb ports are powered by definition. They can supply up to 500ma (half an amp). Dont worry about leaving your tab plugged in, devices are smart enough these days not to overcharge the battery.

Coda is right, technically they all have power . If not, how would any device charge? I guess I really meant to say USB ports charge at a higher MA or something for rapid charging (wall-socket USB adapters?).
Also, Coda is right again. Devices these days are fairly smart. I typically leave my HD2 plugged in all the time with no problems.

itll be just fine plugged in!
ive been part-charging mine at random intervals (sometimes for 20 mins at a time a few times a day) and leaving it charging over a day from both powered hub and charger over about five months... though i have had two or three near total discharges
the battery has got better, which is what you would expect from the tech - sammy even provides a nice notification telling you the device is fully chraged
i wonder if they put that in there to account for unexpected battery problems down the line? in any case, ive read that low-powered charging, even unregistered by the battery, will increase the lifetime of the battery and also charge at approximately the same rate... ive seen this with my phones charging over pc usb

Great! Nothing to worry about then. The tab would look really cool on my office desk sporting the same screensaver as my PC ..'the Matrix' scrolling code.

I think it is OK. I bought a 2d adapter, one for the office. Since Sammy is selling docks, it also means that it can be powered all times. On the other hand I remember my Archos which I used to leave it on its dock all times... battery was killed in a short time. When you sell multimedia charging docks it means that you can leave it there, no? Not in the case of Archos.

Nexus 10 taking more than a day to charge!!

Like the title says, my dad just bought a Nexus 10 and when he was charging it from 20%, it's taken more than an hour to charge to 50%. With that logic, the battery is only charging 30% a day, which means it would take 3-4 days from 0%-100%, and that simply is unacceptable. Is it a defective unit? I know about the Pogo charger, but I'm sure he'd rather not spend $25 on it just to find out it doesn't work.
Any suggestions or ways to fix this?
Thanks.
edit: To make things even sound worse, it only charged 2% in 1 hour and 30 minutes.

All I know is that on mine takes about 9 hours to charge with the original charger. The first time I've charged it from 16% with my Galaxy SIII cable, and it took over 14 hours.

That does seem long. I have the pogo charger and it does charge faster.
Before you buy the pogo, are you using the chargers that came with the N10? When I charge my N10 from a laptop/PC, it does charge slowly. So make sure you're charging with the correct voltage/amps.
Good luck!

I'm having a similar issue since the OTA update to 4.4.2.
I'll try changing USB cables, but I'm not optimistic. I'm tempted to try a factory reset if a different cord doesn't work.

With Wifi on, NFC off, Location set to device only, bluetooth off, screen off, using my Pogo cable I get about 22% charge per hour so from 0% to 85% is 4 hours. Whilst on Pogo if I turn brightness to full and sound full then charge is held roughly flat. I moved to Pogo from the supplied cable as when watching stuff even when connected it was discharging, so now I'm never really out of power unless I stay unplugged a long time (about 6 hours unplugged max on low brightness)

This situation happens when the tablet isn't even on, so certain settings being enabled are not the issue.
And for more info, he is using the charger that came with the tablet, so we've just decided that we'll just send it back and get a new one because the battery is obviously defective.

Have you tried a different cable/charger? AN hour to charge from 20% to 50%? Sounds about right to me. I always switch mine off when charging, I can live without when it' off. :good:

I think clearly a human error in the word chosen explains it.
Instead of "...was charging it from 20%, it's taken more than an hour to charge to 50%. With that logic, the battery is only charging 30% a day, which means it would take 3-4 days from 0%-100%, and that simply is unacceptable."
it would make more sense if written "....was charging it from 20%, it's taken more than a day to charge to 50%. With that logic, the battery is only charging 30% a day, which means it would take 3-4 days from 0%-100%, and that simply is unacceptable. "
.... then the later post of its a dud and its been replaced makes sense....

Ahh, I see. Good call in getting it replaced. I hope you have a better experience.

here are a few points
1) the AC USB come with N10 charge up to 2A.
2) the mini USB limit to about 1A
3) if you use other mini charger, that 1A is even smaller.
4) N10 battery is HUGE comparing to all tablet out there. It will take a long time to charge
Solution: get the pogo charging cable that cost $25 (very expensive and can only use for charging), that will fully charge 2A to your tablet which should reduce the time to less than 4hrs given no other power hog apps running at the same time. It will charge slower if that power hog app running too. You can tell by how warm/hot your tablet gets when running such app.
btw, go look at the disassemble of the N10. That battle makeup most of the tablet. LOL

Agree, BUT once you get >85% the rate of charge intake drops. I can get to 85% in 3.9 hours using Pogo cable, but that last 85%-100% is slower. My battery meter sees one kink 85-90 another 90-95 and a slow crawl 95-100. As the battery is not taking up 2A >85%, all chargers, all cables, will largely take the same 85%-100% but the Pogo cable with 2A input will get you to 85% quicker.
I have moved to a dual 2.1A output PSU.

I know you revised the post but just looked at the link to the PSU you mentioned.
Note that $10 one is dual USB socket but only 2.4A total meaning if it is charging the N10 taking 2A it can only offer 0.4A to something else meaning that other thing can only be something like a phone. More importantly is the opposite if you connect a powerpack USB battery which takes say 1.5A or 2A then your Pogo cable cannot deliver its full capability.
The PSU I mentioned earlier is dual 2.1A both concurrently meaning it can charge the N10 and something else also power-hungry like charging a 2A input or 1.5A input USB battery.
There are PSUs out there which can do 4 lots of 2A concurrent, I didn't get one as they were getting chunky and personally prefer two PSUs, a 2x2A + 1A for total 5A which does my N10, my USB battery (2+2) and my phone (1) concurrently taking two power sockets.
Check the details of specifications of these devices, PSUs and batteries vary wildly.

[Q] Pogo Cable Issue

Hello there developers,not sure if I'm posting on the right place but I have a really big problem. My new Pogo Cable arrived and I was so excited to use it,but my happiness didn't lasted fort too long. The problem is that the Tablet while charging with the Pogo cable is either charging slow ,or neither at all. This issue is available for both Lollipop and Kit-Kat,have upgraded an then downgraded with the hope that the issue will be solved. The original Micro -Usb cable works good but with the Pogo Cable in the Battery Monitor Widget it appears "Discharging" and "AC Plugged",and the charging rate is booring slow. Had the idea to measure the Voltage and the current Flow with a multimeter and got the surprise that while the voltage is 5.12 V the amperage is 0.12 A ,while the original charger pumps up to 2 Amps. Could this be the issue? Is there some electrical switch that should open and release all those 2 Amps or is this Cable a Hoax or something that is not fully functional? Thanks in advance,hope that you guys will enlight me somehow!

I've no idea if this is related but be aware that having your pogo plug connected while also having anything connected to the microUSB will stop charging. The charging icon (lightning bolt) will still appear but that I'd a false indicator. This limitation is due to the Android kernel and is present in all versions of Android.
I exclusively use a pogo plug to charge my Nexus 10 and it has always worked on all versions of Android including 5.0.2 which I'm on today. For me pogo plug charging has always been about 25 percent faster then USB charging.

My experience is exactly the same as 3DSammy reports.

well my warranty is expired so i Decided to "surgically" dissmantle my Nexus 10 in a heroic attempt to find the cause and I have made a breakthrough (or at least I tought so). I got another Pogo cable ,and this one was good,the voltage was exactly 5 Volts measured and the Amperage that I got was 2.21 Amps measured with a 6 Ohm fuse,all these values where from the original Samsung charger. All things good,but the Tablet is still not charging at all,the same Lightning animations and even after 3~4 hours still no charge at all,and this is Lame in my opinion. So after opening the tablet,I got the idea to short the 3 and 4 pogo pins together,and assumed that this will draw all the power that the battery needs to charge,the idea was working i got 20% more power draw than the usb cable BUT for only let's say Half of hour ,and then the same old story,battery was discharging but the lightning animation was on. This is not so good and my suppose is that the Power Management iC from the motherboard is some how not managing the Pogo charge at all :laugh: so my next idea is to wire the charging Pogo pins directly to the battery and hope for the best. Regards! :good:

I've got one of the original n10 from first day of issue. My battery is going to hell after being used and charged every day for the past couple years. It's been on/run everyday since Dec. 2012. I have always had a problem charging while using it. My display is always set at about 1/3 bright. When my battery drops to critical, I plug in the pogo and usually put it in sleep mode to charge. It will quick charge that way.
If I still need to use it at critical battery level, plugged into the pogo plug, it maintains power and possibly gives it a very slow increase in charge. Almost none noticeable, but will maintain power level (unless tons of graphic, camera or movies along with full bright screen).
I've just taken it for granted that this is how it works. Pogo plug will maintain battery while using and will switch to quick charge once put into sleep mode or powered off. It's always acted that way, so I have never known anything different.

Well I'm sure about what did you said,but in my opinion this is a marketing bulls$h*t. Why would I use that Pogo cable if it's role is to charge only on sleep mode and powered off?I ordered because I thought that like the instructions of the pogo says:" it will charge the battery even when you are using it for movies and browsing,being more handy ,because you have the micro USB port free." I play games ,I surf the web,so my tablet is hooked up to a USB hub so I have connected a mouse,a keyboard and a game controller,so my USB port is full,and I hoped the pogo will help. Charging only on sleep is equal to zero for me,I need live charging,in the same time as the tablet runs games and other stuff. In my opinion this "glitch" should have been told on the pogo site,so I could full understand this cable and it's role. Shame on Samsung,30$ .for nothing! Thanks for the help!

Charging Stops Overnight

Like a lot of people I charge my phone over night, but with the 6p I wake up in the morning (after a good 8hrs) and its sat on 96-98%. Even though it still says charging.
It's no big deal but when I unplug and plug back in it charges to 100% relatively quickly.
Anyone else see this? I'm using an older charger (from my nexus 4) so may try the proper one tonight.
Sent from my Nexus 6P using XDA Free mobile app

Isn't this normal behaviour? Most phones stop topping up the battery even when connected on the charger to avoid wearing off the battery.
I used to have my HTC m7 connected overnight to the charger and even though it showed 100℅ in the morning, as soon as I disconnected it from the main the indictor would drop rapidly to ~95℅ which indicated the above behaviour.

I've not seen it before. My galaxy s6 always came off charge at 100% as did my nexus4 and the 5x I owned briefly.
If this is normal and happens to other 6p owners I'm happy with that

Mine is doing this as well. It seems to charge to 100%, stop charging, and not run off power at all. Since I use sleep tracking, in my case, I usually wake up to about a 90% charge. This is the first phone I have seen do this -- they usually charge to 100% and keep running off the charger. I haven't tried the stock 3A charger yet, as there really is no need for a quick charge overnight.

How in the world are you using an old charger on a Type-C Connection? (or are you using a converter?... if so, that may be the reason)

Just using a USB A to USB C cable into the power brick from my old phone.
Pretty straightforward really.
I'll try with the proper charger at some point. It's not a big deal.

Mine hasn't done that. Got it Thursday and it's had a full charge each morning. Using the supplied charger

normal behavior. it does that to protect the battery.

Every phone I've ever had charges to 100% and stays running off the charger to stay at 100%. Last night (my first night with the phone) I plugged it in with 31% and woke up with it at 81%. It clearly charged....and then stopped charging only to run off the battery while still plugged in. Not normal for any other device I've owned. I would prefer it to stay at 100% until I'm ready to unplug it. Maybe using the supplied charger will do this. I used a USB A to C cable plugged into USB wall port. I have replaced several outlets in my house to ones with built in 2.1A USB chargers.

Why should it matter? wattage is wattage. Does the phone charge differently with the stock charger? Do you always carry it in your back pocket? Do you ever use a car charger?

Carry the phone in my back pocket? No, I don't but what does that have to do with the price of tea in China? I do not use a car charger either. As for wattage, I believe that the type C 3.1 chargers output at 100W and possibly 200W whereas the one you are using might deliver 18W. There might also be damage due to wiring with some of the 2.0 - 3.1 adapters but I'm still researching that.
So why wouldn't you use the type C charger? Besides, you can't plug it in backwards or upside down. And once you get a computer that supports type C the data transfer rates will be astonishing from what I've read.

Do you carry STOCK charger in your back pocket.
Point is, sometimes I need to charge it at work, or elsewhere as I may use it heavily. That's why I would use another charger. Point is, why does it stop charging on the charger and not draw from the charger once it's full. Like I said, mine charged fully then stopped using the charger drawing from the battery. Kind of pointless if I leave it on the charger to be full when I leave in the morning if it's not going to be full.

I'm glad its not just me who finds this a bit odd.
I used the same charger with my nexus 5x, galaxy s6 and nexus 4 and always found the phone at 100% in the morning.
The 6p obviously works differently.

I see what you mean. For a quick boost charge I can see you carrying a cord in your back pocket. I'm really trying to get a full 14-18 hours with this device no matter my usage. If I can't I really cannot justify this expense. I have 4 phones on my plan, a Samsung 5S, two iPhones 6s, and up until yesterday my N5. All other 3 got a full day plus even watching video and listening to music constantly. So no, I'm not carrying a charger, a cord or buying a car charger.
As for your problem of charging, have you tried the stock charger to see if you can get to 100%. I have already twice with no problem. Last night I wanted to unplug it once charged to see how much it drained overnight but I fell asleep at 93% and unplugged a few hours later. 6 hours off the charger it was still at 99% so I'm assuming it charged to 100 or close to it. Perhaps you can do a full charge overnight and then a spot charge during the day if you need. I'm thinking you might not.

I am also having this problem. I am using the included c to a cable to charge with. The phone stops charging around 95% and doesn't charge ever again until I unplug it and plug it back in.
These are the problems with this:
1. Cases where i do not have the included charger with me.
2. On long trips where my phone is plugged in all the time to prevent it from dying. (Streaming music, navigating, etc)
3. Sleep tracking
I'm using the Anker 5 port charging hub at 2A each port.

once your battery gets fully charged 100% - the charging stops to prevent your battery from overcharging. since your battery is not charging - your battery will drop down. once it gets down to 95% - charging resumes until it gets back to 100%.
in other words - that is normal.

Every other phone I have ever had did not do this and instead trickle charged at 100% and ran everything off of the charging port, never had a phone that constantly drops to 95% then back to 100%, that would be a roller coaster during car trips. The problem I'm experiencing is not that situation either; the phone will stop charging and never get charged again, so it could drop to 80% while connected to the charger. It knows it's connected to a charger, but doesn't draw current from it. Doesn't show the charging icon or charging AC, but the lock screen shows the percentage of battery.
I do have possibly some positive observations however. Last night I decided to try it without my USB 3.0 extension cable, and only the measly 1 foot c to a cable Google provided. Without the extension cable my phone charged as it should, went to 100% and stayed there with the charging symbol still on the battery icon. Upon removal of the charger, the battery stats showed only 3 seconds of use, whereas before it would just show everything since last 100% (which was sometimes 50 hours even though i charge my phone every night). I'd have to keep observing this to see if it was indeed the extension cable.

That's interesting wrt the extension cable. I have a extension as well. Will get rid and see what happens. I keep meaning to try stock charger and stock cable but can't be bothered.
It's not normal behaviour or else it'd happen on other phones. I've had nexus 4 iPhone 4s htc one m8 Samsung galaxy s6 iPhone 5s and nexus 5x all using the same charger / extension all have charged to 100% and stayed there.. Except the 6p.
It's not a massive deal, typically it'll loose 1 or 2 percent over night once it's been to 100.

Just an update, it was the extension cable. Phone charges to 100 at stays there until unplugged as is expected behavior. Just don't use USB extension cables to charge devices
