hi just have a question, howcome my newly bought xp 2000 energizer could not fully charge my sgs2? seems that it can only charge my phone 80%.
These were the following conditions when I used XP 2000:
1. xp 2000 was at full charge
2. my phone was turned off
3. my phone was not drained, still had around 10% charge.
I noticed like around 80% of charging, a temperature icon showed blinking as if the battery was heating up(sorry i don't have a screenshot).When I tried to unplug xp 2000 from the phone, the charger no longer have lights on, as if it got drained w/o fully charging my phone..
This is my 2nd of unit of xp2000. The store where i bought it replaced the first one thinking that it might be defective but same goes for the new one..
the temperature icon I mentioned only shows up whenever I use xp 2000.
Well the Charger can store some amount less than 2000mAh of Energy. The SGS2 battery is rated at 1650mAh. So in theory you have 350mAh of additional power in the pack than you should need however the battery is still draining while it is being charged (the SGS2 can draw up to 1A current according to specs and even in the deep sleep state I wouldn't be surprised if it draws 50-100mA since the hardware doesn't support true power gating. I mention earlier that while the charger is rated at 2000mAh it can probably on store up to 90% of this value aka 1800mA.
In summary:
The capacity of the power pack is closer to 1800mAh that 2000mAh.
The phone draws significant power even in deep sleep.
There is additional power lost by transmission and charger control circuitry in both the power pack and the charge controller in the phone.
There are additional reasons but those are the main ones.
That is why you cannot fully charge it with a power pack.
Please press thanks if you find this information useful.

ok thank you! one rep from energizer had somewhat a similar explanation.Well, I guess I'd have to accept it as is... If only I knew, I could've bought one that has a higher mAh, like xp 4001... so sad.... anyway appreciate it!
On theory, a 2000mAh is capable of charging a 1650mAh battery as long as power is not lost through other means.
Most of these battery packs do not have a Zener Diode, you might want to modify it to add it in. This will allow your 2000mAh pack to charge your 1650mAh battery for 1 time only.

How can I modify it? sorry..
I use an xp2000 with my S2 - but I think of it as a battery extender, rather than as a primary means of recharging it. I use it when I'm working & the battery's getting a little low - it can keep ahead of the phone and gives me another 3-4 hours in total. The great advantage (over a spare battery) is that I don't have to power down, so if I'm downloading, for example, and I don't think the battery will make it to the end of the download, then I just plug in the xp2000 & the problem is solved.
I have lots of different ways of charging - mains & car chargers, USB cables, spare batteries - and find the xp2000 is a useful addition that sometimes saves the day. It's just the right size & weight to be able to carry around without having to think about whether you really need it - so it's always there when you do.
If you're using any state-of-the art smartphone intensively, it helps to have a variety of recharge options, and to take advantage of any opportunities you may have to top up during the day, thus keeping ahead of the phone's discharge curve.
What do you think about the solar charger available on the bay?
Link?
There are a few solar charger systems out there... I am currently reviewing this one http://www.amazon.com/Multifunction-Portable-Battery-compatible-smartphones/dp/B0091PLQ08 for The Gageteer... and I think these are the most usable systems unless you want to haul a giant panel around (and you are in the desert )
The panel generates enough juice to slowly recharge a fairly large battery, and then you use that battery to recharge your USB-charged devices.
I've seen direct charge solar panels, but they're either too low powered to charge anything quickly (the panel with the r.pod manages 1.65W in full sun) or too damn big to carry around - so a panel to battery (most of a day) to use to recharge device over night works out pretty well.

Hi,
How long does it take for you to charge the battery?
I'm using the bundled charger and wifi is on. No apps are running and the screen is turned off.
It's currently at 19% and remaining charge time is estimated to 1 day 3 hours (=15 hours from 19% too 100%).
When browsing (using wifi) the tablet complains that it's using more power than it receives.
Is this normal?
With a bundled charger it should take about 6 hours. Maybe the charger or cable is broken. Check other charger. Install Current Wigdet and check charging current.

Did you try to reset it completely? Maybe some apps in background are using power. I've got that message only when i was playing resource hungry game and recording it.
Im have Checked the Power.
Thanx „awionetka“ for Tipp Current Wigded
My Value: WLAN On

Judging by your numbers it looks like charging current is lower than power drain during gaming. This can happen with some games. With qualcomm charger it should take about 2:30 to charge 0-100 when completely idle.
Got both Autek QC and CHOETECH QC. With the later I can play XCom EW with ~10% battery loss over 2 hours. With a regular USB2 power connected I got "current is not enough blah blah". With no power connected this games drains battery at a rate ~30-40% / hr.
I'm quite happy with the result. Don't really care if it charges it fully in 2 or 2.5 hrs
I have contact Sony for the to little Power Supply. Sony tell me this is normaly. I say this is a Bug.
Acer Tablet A511 Charge with 12 volts. Sony must incrace the Power. The Charging Bug similar to other Sony Z Smartphones. The Bug ist not unknown.
Do some math!
The battery is 6000 mAh capacity.
https://en.wikipedia.org/wiki/USB#Charging_ports
Maximum current within USB specs is 1.5 A. You will not get 100% of the juice into the device due to inefficiencies.
@Koto99:
In Germany in an average household you can even use 230V. Why stop at Acer's measly 12V?
@DHGE
If the USB Charging is to low for delivery the Power for the Device. Sony must build a normaly Power Connector.
USB Charging ist not a must or?
Acer can do what Sony not can do?
Ok, Acer Connector is not a Standard Connector. A Combination from Acer Connector and USB Slot.
Why Acer stop on 12V no idea
I mean the Charging with 220 Volts are to big and Damage the Accu.
When in the Future Displays come with 4k or more Resolution. And more CPU Power. The USB Charging have no Future.

For me it is a must.
I despise proprietary solutions, not having source code, dongled consumables, DRM infested SW ...
USB 3.1 can negogiate up to 100W over USB. Current Android devices are at best USB 3 speed with USB 2 power specifications.
Bitten fruit do some tricks beside the specifications for a 30% gain: look at their accessory prices.
I guess (looking at my really expensive LiPos for flying my planes) one could feed up to 4A into the Z4. So charging time at best before damaging the battery or melting some circuitry in the charging chain could be 1.5 - 2 hours for a 6Ah battery.
when attaching the Incipio Power to the phone gives me 94% of the battery, then after 3 sec give me it is 0% also this happens when charging both phone and the Incipio when the phone is power off, using the Turbo power charger which comes with the phone, and the plus image which indicates that the Incipio in charging the phone not shown at all. could you please advice.
Anyone using this battery charging case? Bought one from Amazon a week ago, it works great but there is one problem.
As we know when just charge the phone using any USB C cable. I usually charge it at night when I goto bed, so when it charges the phone up to 100% full and the phone will remain 100% unless I unplug the charger (doesn't matter how many hours or days)
But if I put the Alpatronix battery case on my phone, when I charge it all together (according to the manual , it was programmed to charge my galaxy s8 first then battery case) When my phone reaches 100% it stopped charging and I can see the battery starts draining even though my charge cable still connected. This is what I don't understand. I tested it with straight charging cable and wireless charging. Both end up the same with the Battery case attached. It will charge my phone and the battery case for sure, but it stops charging while my phone reaches 100%. And when it starts draining from 100 to 99 and so on. It will not automatically charge my phone itself till it is full. It will only charge the phone when I am not using battery case. My phone will remain 100% all the time with charge cable connected. No matter how long I have the phone connected to the charger, hrs, days. It will keep it 100%. I wonder what is the main problem? Would it be a defective Alpatronix battery case?
I think it is normal?
I've had many kind of power bank, which is the same principle as battery case. Most of them stopped charging when phone battery is full, and yes, you need to initiate the charging again if the phone battery starts decreasing (usually by pressing the button).
Well, there are several "smart" power banks that starts charging when you plug in the phone, and does trickle charging when the phone is full. But, what I want to say is that not every power bank is made of the same system.

Are you talking about power bank or battery case?
If you know any battery case that has the feature I mentioned above, can you give me the name?
I have a few power banks but I don't like carry it separately. Battery case is more convenient.
