Default How long does the battery last on your DROID after conditioning?

Describe your usage and how long it usually lasts you. This is only for people who have done the battery conditioning.

Thanks!

Battery conditioning is "When you intentionally discharge a battery down to a certain minimum voltage and then recharge it this is known as battery conditioning or reconditioning . It is also sometimes referred to as battery exercise. This is particularly important to reduce what some call the memory effect experienced using NiCD batteries if you habitually do not fully discharge them each time you use them. For NiCD batteries this must be done periodically, approximately every 10 charge/discharge cycles or so, or the batteries will begin to lose capacity. For NiMH batteries conditioning is not really needed to reduce any memory effect because that is negligible in this type of battery. However, reconditioning is very convenient for both NiMH and NiCD batteries because brand new batteries are not charged when you receive them and they must be charged and discharged three to five times before they reach their full capacity. In addition, occasionally conditioning rechargeable batteries helps to ensure that they give you years or service and save you as much money as possible, before you recycle them and get new ones."

This also applies to Lithium Ion batteries such as the BP6X sitting in your Droid.

in layman's terms, it means after fully charging and fully discharging your battery 3-5 times.
This will solve a lot of the battery problems people are seeing with this phone.

I know conditioning has been suggested many times in this forum but it just isn't necessary. A quick google search confirms this on just about every site/article...

Anywhere from 12-18 hours depending on usage. However, as of today, I'm @ 80% after 8 hours of usage.

That's odd, Seidio, an aftermarket extended battery maker, states that "conditioning" is required, as part of the directions included in their packaging. Both of my Droids also had poor life their first few days...after about a week with each one, I was able to get a full 24 hours with normal use.

No, it does not apply at all. You should not regularly drain Li-ion batteries like you used to do with older types of batteries. In fact, regularly discharging all the way is more likely to cause harm than good (although it's okay to do it once a month or so to calibrate the battery indicator).

You should charge as often as you can.

All lithium ion batteries need to be calibrated. Notebooks, GPS, phones, etc.

to do that do you need to like it discharge completely? b/c I haven't done that yet and I'm worried my indicator isn't accurate.

Yes, you must drain it completely so that the phone won't power on at all.

I was getting about 8 hours before conditioning, now I am at 14-16 hours, depending on usage. Believe what you want, Google what you want. Condition your battery, it works.

No, it's not. It will trickle the charging once it hits 100%. Unless you're leaving it plugged in for days on end, there is no harm in letting it charge.

what do you mean trickle the charging? and I'm more referring to that even after it's fully charged I'll leave it plugged in if I'm near a plug.

The phone will automatically slow the charging to a crawl once it hits full charge, therefore not causing any harm leaving it plugged in fully charged.

My droid eris just died after 22 hours from al day of moderate use. Running down the battery once and charging up has already improved my battery life dramatically. I thought the Motorola droid was supposed to have a better battery and battery life than the HTC eris? I was considering switching to the droid because I thought I would get better battery life. After seeing the hours posted here I'm not so sure it lasts longer anymore... so now I'm confused again??

That is something I like to refer to as "newness wearing off". You use it non stop for a week, and then it just becomes a phone again.

Battery conditioning was part of the old Lithium-ion batteries that would develop a "memory" when not fully discharged. It does not hold true to newer generation batteries. The belief that it will help is, at this point, much like the belief that cell phones will crash planes or blow up gas stations.

So in brief, any of you who believe in conditioning were, not too long ago, correct. But the world turns, life changes, technology advances, etc, etc, etc.

16 hours in and my battery is at 50% right now. The battery does get a lot better after calibration and a few full charges.

Here is an inmportant quote from one of the above articles,

"A lithium-ion battery provides 300-500 discharge/charge cycles. The battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible. Instead, charge the battery more often or use a larger battery. There is no concern of memory when applying unscheduled charges."

Battery is only rated for 385 minutes of "constant usage"...60% after 3 hours seems about right. Just wait for Seidio's extended battery.

I was using my "2nd Droid" as a "phone"...both had poor life in idle state during the first few charges. With my Moto Q, I had it for over a year prior to picking up the Seidio. The Seidio also held charge poorly for the first few cycles. You may not need to completely drain the battery, but its definately not at its peak in the beginning.

I'm not sure the % meter is linear so I don't personally depend on that to suggest how much *time* I have left but only as a rough guide.

However, I am getting anywhere from 10-16 hours of time depending on what I am doing. I haven't yet documented all the scenarious and the associated "up time" for my Droid. There has been a couple of occassions where I really didn't use it much and got closer to the 10 and other times it seems I was using it a lot and got closer to the 16.

So I am continuing my "unscientific" documentation of what is running and how I am using it.

The surest way to test the battery usage by various services (GPS, screen, Wi-Fi, calls etc) is to insert a milliampmeter between one of the battery terminals and the phone, and record the current drawn when using those apps/services. I have done this by inserting a strip of two-sided adhesive tape with two very narrow strips of copper foil on the two surfaces; the strips are then connected through a recording multimeter or simple data logger. If in parallel you'll record the terminal voltage of the battery, you can easily calculate the power drawn during each service/program test (P=U*i).

As you can imagine, there will be an almost inifinte number of combinations and parameters to conside under varous use conditions, thus giving an average battery life may, or may not, be very useful. For example, the power used during a phone call will depend on the signal strength and sound level; the former, in turn, will depend on the distance to the trasmission power, atmospheric conditions, location etc etc.) Any number you'll see quoted around will easily have a +/-50 % error...

I don't have a Droid (am waiting for the Milestone release in the UK) but I've found the same thing with my last 2 phones both using Li-Ion batteries, I think it might be a case of the phone needing to calibrate itself. So the batteries have no 'memory', but maybe the phone isn't able to get a handle on how much juice is left until it has seen a complete full-empty cycle?

Default Force discharging the battery

Can I (force) the battery to discharge quicker by never letting the screen timeout and playing music? Will this hurt the battery?
I need better battery life,thats for sure. I'm only getting about 5 hours till its 20% or so then I recharge. But as any other person,i've been ******* with the phone non stop. downloading apps and such. If it's ok I will drain the battery as mentioned above and recharge a few times to hopefully gain a bit more battery life.
What do you all think?

Turn your phones screen on, turn on Latitude, and leave it running. I do it every night, and if it isn't plugged in, the battery is drained in 3 to 3.5 hours.

Is latatude an app? is it free? Or where can I find it? Is this the fastest way to drain the battery? What about hand warmer? Is it safe to rapidly drain the battery?
Lot of questions,huh?

A typical cell phone battery should easily and safely handle a 2C-rate discharge (a total discharge in 30 minutes), but it will generate a decent amount of heat. This is because a battery has an internal resistance (for a 1.4 Ah prismatic battery, it is probabaly somewhere in the 60-100 mohm range, thus a 2C rate would be 2.8 A, from which you can calculate the amount of heat evolved and, approximately, the maximum battery temperature...)

Li-ion batteries do NOT need to be conditioned to work well; what needs to be conditioned is the circuit/device that measures the state of charge (coulomb counters etc.). In principle, the state of charge of a cell can easily be determined for a given battery chemistry from its OCV (open-circuit voltage), but since the cell voltage depends on the currrent load, other means (coulomb (charge) counting circuits) have to be used under practical variable load conditions... For general examples, look at figures 2 and 4 in http://www.intersil.com/data/an/an126.pdf

You can go to How to prolong lithium-based batteries and you will learn everything you could ever want to know about our Li-ion Batteries.

10.5 hours unplugged, 60% battery left with Heavy Usage. Impressive for a smart Phone.

I'm getting anywhere from 10-15 hours before the Droid tells me to plug it in (10% battery left). It all depends on usage; sometimes less if I have a lot of conference calls. For the first 3 weeks or so I had screen timeout at 30 seconds - since then I decreased it to 15 seconds - that helped to make the battery last longer. There's an app to toggle screen timeout on/off that I've been playing with for apps like browsing when I'm not always tocuhing the screen - reading articles etc. Display is almost always the # 1 user of battery(although I just checked and today it's voice calls). I keep it plugged in in the car.

it all depends on usage but here's my thing

I can get 15hrs with 40% left after 1 hour of voice call, some emails, and sms. I have brightness at like 30% or so and have home++.

Lithium-ion batteries do not have memory issues like the older nickel-cadmium, so you don't have to fully charge or deplete them to increase battery life.

The only reason you would want to fully charge or fully deplete the battery is so the "battery Status" indicator is very close to to batteries actual charge. So if the battery is completely charged the white battery icon is actually accurate.

My battery longevity is much less since the upgrade to 2.01. I am getting about 7-8 hours. I haven't been able to pinpoint the reason yet. I notice GPS is always on today and tried turning that off and it seemed better. Then I turned on the 'always push' for my work email and it started draining again. Somewhere during the day GPS started again and the battery went down quickly, but I am unable at this time able to tell if it is strictly GPS on or always push on the email. Either way it was much better prior to the upgrade.

Of course I continue to try different stuff like Home++ and now the phone is really starting to lag. I hate to give up on Home++ since it is much nicer than the stock Home.

I'm considering a factory reset, but I need to search on the forum to understand what the impact of that is.

It sounds as you have way too many things running on the phone. Isolate those problems and you will gain more battery life.
