Battery Results after charge/discharge cycle

Winfield wrote:Well I did the test and cycle. My maximum battery life with a few text and calls was from 8th July 6 am to 10th July 8pm. 2 days and a half. Still poor. Phone in GSM mode, didn't use any smart aplications, sleep mode on, light sensor down by one notch, no open aplications, almost always with full network coverage, etc.
Just plain simply disappointing.

@Cash
Unlike you I "can't live" without the camera. I use(d) it all the time on my K750i, specially at night.

Your complaining at 2 and a half days? WOW what do you want?

yea, If I can get up to 2.5 days I will be well happy 😊..

Maybe they just have an unlimited amount of monkeys messing around with electronics and this is what they came up with 😊...give the monkeys a calculater !!!!!!!!!!!!!!!!

Somebody at Nokia probably got quietly demoted/sacked/blamed by the real culprit etc. I would not be totally surprised if they release an N80i in 3 months with a higher capacity battery, enhanced (de-bugged) firmware etc.

D😎

@Jayd

But in real life I will never achieve that long again. It was only a test I did this weekend after the charge / discharge cycle. Only got 2.5 days without using the mobile (3 or 4 sms, 1 or 2 calls).

Duplicate post Due to server busy...

I am amazed with people complaining with battery life etc... but overlook one single most important factor: Operator Signal.

1) If you are located in area with good coverage, the power drained during no-activity is very low, and vice versa. If you're keep getting anything lower than full bar of signal, it'll transmit more power.

2) If you're roaming in other countries, your phone most likely change from one operator to another. This requires higher power usage and thus consume the battery faster.

3) If you're driving a lot or moving from one place to one place, you may change Base station frequently, thus increasing power drain as it needs to update the operator where you have moved.

Wanna have a consistant test result? Use it in offline mode and play a single standard songs repeatedly, this you can compare apple to apple not apple to oranges.

I'm using latest version v4.0623.0.36 soon available in Nokia service center. Don't ask me where to get the firmware!!

tell us more about that firmware..

i cant wait to get my hands on that.

Your points dont apply to my test, we live in the real world and product should be tested as such, not in optimal conditions as nokia tests and releases their data, I live in the center of a capital city wih an antenna not too far away, I have full battery strength, and when I made my test the phone was kept at home for the whole of the test near a window where the mast overlooks, and I still only got 18 hours battery life after only receiving a dozen text messages and 2 very short calls,

Thats why I am complaining about my battery strength !!!!!, and I assume the reason why everybody else with a poor battery life is also.

If it was just one or 2 people then fine I can see something may be wrong with the phone or the settings, but there are a great deal of people who are using their phones as they should be used, dont forget its a smart phone not just a phone or an MP3 player and they are getting way less than 24 hours, in my books this is not acceptable and as I have stated in other posts Nokia has released this phone with an inferior battery that is not up to the job which it is intended for .

Sorry to preach but its a very big problem when out and about and the phone dies.

Just an update on my battery life with phone in sleep mode and hardly any calls or text messages, and no other apps being used

I am on 50 hours now since the last recharge and the battery indicater has only dropped 2 bars.

Remember though I am only using the phone now as purely a phone and not using any other feature of the phone, and its in sleep mode.

If you want Nokia to listen post it on their forums, why should they monitor here for problems with their phone?

That screen grab looks photoshopped if you ask me. You have no launguge after Nokia N80 ie (08) and you have no network provider even though you have a 3G signal.

Nokia dont let people with grievences post their views on the Nokia forum, they either censor edit or close the thread down.

Just go on there and have a look

@Cash
50 hours and only 2 bars drop? How much do you want for your battery? Seems great. With that usage I only got 60 hours autonomy as I said in previous post.

Hi winfield, you need to read my posts correctly.

I have 50 hours, thats not using the phone as a smart phone but just as a phone, without BT, wifi, gprs and without playing games, music, video, browsing the web, sending mms, using the notebook, office, connecting to my computer and installing programs and using these programs, taking pictures and video....well I think you get the idea.

If I just wanted a phone to use as a phone I wouldn't have paid �400 on the N80, I would have gotten one for free.

This latest test was to see the longest I could get out of my phone with the absoulutely minimum use, with everything switched off and the phone in sleep mode, I f I use the phone with normal use I get just 18 hours charge although I need to do another test with sleep mode activated as I mentioned in a previous post,I dont want minimum use I want normal use.

Hope you understand now.

@Cash
I read your post correctly. That was the same test I did. Sleep mode activated, GSM mode. Wifi off. BT off. No camera, video, gallery, apps. Nothing. 2 or 3 calls, 5 or 6 sms and got only 60hrs off it.

Ok I see...I didnt read your post correctly, accept my appologies 😊..

Well the battery actually only lasted 60 hours anyway, the final bars seemed to dissapear rather quickly.

I removed the operator text and variant information (..) for anonymity reason. But i do have the firmware 😊

Anyhow, I know the battery life is worse than others. But I always have two nokia charger in my desk. When I'm working in my desk, I plugged them into the charger. When i'm my car, I have a carkit that charge the phone.

On top of this, I always carry extra battery in my suitcase...

So battery is not a problem.... When I use firmware 1.x.x.x, the battery life was only 2 hours 😊 but now it has gone better...

So whats the problem in sharing it if you have it?

I've just completed the 3 cycle recharges and have to say I've seen a vast improvement so far in battery life. Since finishing the final charge yesterday I've made a few calls prob about 15 mins in total and sent some texts out. Played Snakes for about 10 mins last night, used alarm this morning [snoozed a couple of times haha] and had a missed call ring out this afternoon also used planet 3 for about 10 mins. Phone is still on full bars over 24 hours later!! Result!!! I have bluetooth and wifi off. using a theme called 'dark' or something similar and have all of my power save settings to maximum ie shortest timeouts etc. Screen illumination is set to medium. I have 3g still enabled [when i have signal] but it's still looking for it. I'm probably still gonna keep my eye out for a battery with a hight mAH value as longer the better is still the case but at least I'm getting resonable life out of the standard batt.

I have just found this site about batteries if anybody is interested in taking the time to read, look for lithium - ion in the table

http://www.batteryuniversity.com/partone-23.htm
http://www.batteryuniversity.com/partone-21.htm

It appears ther are a number of key issues with the lithium - ion battery

1, they DONT need the initial full charge that we are all told they need to get full capacity.

2, they DONT require any charge/discharge cyles, except for once per month is reccommended.

3, full cycle charging should be avoided as this creates wear and full discharging should also be avoided, low voltage may cut off safety circuits.

4, its recommended to charge more often while the battery has capacity then to wait for a full discharge and then do a complete full charge, the battery lasts longer with partial rather than full discharges

so as my battery discharges every day with normal use and I have no means to charge it up untill I get home, then have to apply a full charge over night this does actually damage the usefull life of the battery!!!!!!!!!!!! and surely that has to be seen as a fundamental design flaw of the N80

Right, well my new battery should be here by tomorrow. Im gonna put it on charge as soon as i get it, leave it for about 3-5hrs then use it itll 3 bars and recharge. Im just gonna send my old battery back to Orange and forget about the 16hr charge, fully discharge cycle.

Hopefully it'll be fine. What people thinking? Follow Isidor Buchmann?

Mr Buchmann gets my vote,

When I did my 16 hour charge/recharge cycles I didn't see any improvement at all in the life of the battery.

I dont actually think these batteries are as tempremental as we are led to believe, I have even taken batteries back before and the assistance have told me that they wont replace if I didnt go through the initial charge period, i think its just an excuse to get out of giving a replacement.

If the initial charge was that important, then all batteries would either be supplied fully charged, or fully discharged, not partially charged.

Cash - I dont actually think these batteries are as tempremental as we are led to believe -

I believe that nowadays, the batteries (Li- Ion / Li - Pol) are as the engine of the cars, already they had been tested in board, before came out to the market. On fact its duration does not depend on the initial form of the use!

Agreed, if the initial charge was that important, then they would either be supplied fully charged or fully discharged, not partially charged as they always are.

well i have to say something, im pretty happy with my n80s battery cuz im not getting those problems of 3 hrs of usage, im always connected to wifi, i use agile messenger a lot im always cheking my mail, openning pdf and docs, like 10 texts per day a couple of calls like 15 mins per day, and when i get home i swich off wifi and i still get 2 bars on phone, i plug it to charge at 12 then i wake up at 7 go and take a shower i unplug it like 8:00 and i go office, then i switch wlan on, wlan its turned on like 6 hrs and a half and i have bluetooth always on, i use GSM and GPRS there is no 3G on mexico my firmware is the latest flashed with the .08 firmware file, i bought it like 3 month ago, at the beginning i had to use my secondary batt that is on my wallet (this is the one that came with the phone), i bought my BL-5b batt from a nokia service center and its the one im using right now because i noticed that the replacement was better than the factory battery it lasted a lot more.

Wow, good to hear that somebody is able to use the phone as it should be used, if I put my wifi on I am lucky to get 2.5 hours before the battery gets flat, may try getting them to change the battery and see if I get an improvement like you,

My battery went flat again last night at about 9 pm after a full charge the night before without much use of the phone 😞

One thing that anoys me is that on my phone there is no warning that the battery is low and many times the phone is switched off because I didnt know the battery had died, anybody else noticed this.

It�s strange! I do not say that yes or that not, but it�s strange. Nowadays the production of this type of materials, is carried through accordance with rigorous processes and standard, then to have great discrepancies between devices and batteries will not have to happen. It has a factor of great influence, the net of the operator. But this factor only, couldn�t imply great differences in the duration of the battery. Is strange!

I have been reading some of the old pre release reviews of the N80 from last year and the begining of this year, and many of the reviews said that the 2 main dissapontments, and possible saleability issue with the N80 were the poor camera quality and the dissapointing battery life.

Do Nokia not listen to the feedback from these reviewers,

These were known issues before the phone was released, and as such should have been rectified

Ok I am not going to go on about the battery anymore, I think I have said enough and I cant really add anything else that may be constructive 😊

Same to me. I�m tired to talk about battery life. If samebody wants a brave battery life, use a 6310i - a champion. The others, over all the recent symbian phones have more or less limitations. That�s it!

Guys,

For what it's worth, the battery on my N80 lasted 4 days - admittedly i'm not using all the features - a few 2 minute calls, some 40 odd texts in and out, wifi for about 10 minutes.

Still, it's not that bad is it?
