Battery charges slower then i use it
 
Hello,

i plugged out my phone today morning with a charge of "84%". Right now it's connected to the charger (all the day) and here we go:

Code:
root@Nokia-N900 ~ # lshal | grep battery.charge_level.percentage
  battery.charge_level.percentage = 1  (0x1)  (int)
Too bad. Somebody got a idea how to get rid of that? What about when i want to disconnect and go out a bit now?

I am using Internet (3G) over my Nokia N900 with Joikuspot - but even USB does not help ....

Something to bare in mind when checking the battery level is that it isn't updated until after you take it off charge.

I did. After 2 Minutes waiting here we go:
Code:
root@Nokia-N900 ~ # lshal | grep battery
  battery.charge_level.capacity_state = 'low'  (string)
  battery.charge_level.current = 1  (0x1)  (int)
  battery.charge_level.design = 8  (0x8)  (int)
  battery.charge_level.last_full = 1  (0x1)  (int)
  battery.charge_level.percentage = 0  (0x0)  (int)
  battery.charge_level.unit = 'bars'  (string)
  battery.is_rechargeable = true  (bool)
  battery.present = true  (bool)
  battery.rechargeable.is_charging = false  (bool)
  battery.rechargeable.is_discharging = true  (bool)
  battery.remaining_time = 0  (0x0)  (int)
  battery.remaining_time.calculate_per_time = false  (bool)
  battery.reporting.current = 5  (0x5)  (int)
  battery.reporting.design = 1265  (0x4f1)  (int)
  battery.reporting.last_full = 5  (0x5)  (int)
  battery.reporting.unit = 'mAh'  (string)
  battery.type = 'pda'  (string)
  battery.voltage.current = 3563  (0xdeb)  (int)
  battery.voltage.design = 4200  (0x1068)  (int)
  battery.voltage.unit = 'mV'  (string)
  info.capabilities = {'battery'} (string list)
  info.category = 'battery'  (string)

If you are charging with USB, this happens and you should try another connection.

Did it ever work?

I use a separate charger. It cost about $10.

I charged by wall charger, now i put to usb, still 0% but i will keep it in for some hours and give Feedback over here.

Edit: Now i connected a No-Break between charger and Energy, maybe it's just shitty energy today. We'll see. Still using wall charger now. But i think it will not solve the problem too...

Edit 2: I think it's Joikuspot. I connect now to direct USB Connection over Nokia OVI Suite. Let's see if it's getting my phone charged. But maybe somebody elese have that problem when using N900 as a 3G Modem?

I installed BatteryGraph now and logging there the charge in %, hopefully it's working when it's connected to a charger - does it?

Right now I found out:

If the internet 3G is disconnected it charges - wallcharger or USB - if i use the n900 as a modem it will not charge sufficient. Have somebody the same problem here?

Report to joikuspot and explain your situation. Sadly itīs holiday season so I would wait for at least week for answer :|

Believe it or not: After a reboot that issue is solved.

Maybe because due a kernel update i made? Funny.

Joikuspot adds a constant 300-500mA drain. Charging from a USB host would at best keep the battery level from falling.

Add 3g on top, which can consume 200-600mA extra, and you'd be losing charge fast.

The maximum charge from wallcharger is 950mA, and connecting it makes N900 draw 100mA extra since PR1.3.

The power balance is thus -300-200-100 + 950 = 350 at best and -300-600-100 +950 = -50 at near worst.

Using usb instead of the wifi is a drop of 300mA in consumption, but USB host is limited to 500mA.
Thus you have a range of -200-100+500 = +200 to -600-100+500 = -200
