This guide is not meant to be as a whole and is not meant to be followed from beginning to end. There are several recommendations based on my own experience, some of them will give you big battery savings, some of them minor ones; I tried to recopile every config that helps to save battery, but every config is not suitable for everyone. (I´ll point it at the beginning of every section in bold blue).
You'll need a Rooted Galaxy Nexus, with a custom ROM and a custom Kernel.
The custom ROM will give you the ability to make a deep configuration of the device in terms of options. I'm actually using Liquidsmooth v1.25, but AOKP, CM9 and SlimICS have the same options (if not more) than my actual.
Some custom Kernels will give you the ability to change the CPU frequency and voltage, kernels are the main reason of some drainings or fantastic battery life, choose wise.
The normal Galaxy Nexus battery life is about 4 hours screen time. If you are not achieving this, the main reasons could be:
1. Some apps are draining your battery due to a continuous use (no deep sleep or continuous wake ups).
2. Screen too bright.
3. Bad kernels with draining problems.
4. Weak signal connections.
This guide is wrote by me, a simple user that is sharing his own experience of the last 4 and a half months with the device. Some statements may be wrong. I'll appreciate any positive recommendations in order to improve the guide and help the rest of the community to achieve the best battery life the device can give us.
I'm using actually Liquidsmooth v1.25 and PopcornKernel, in a GSM GNex with standrad battery (1700mAh), and I'm getting this results:

SCREEN
Due to the big screen, this is one of the elements of the device that affects in a major way to the battery live. (Great Savings)
It has been checked that black themes have a great impact on the battery due to the fact that one black pixel does not consume any battery.
Some apps have a black theme option on them, if you choose it you will save some battery.
On the other hand the brightness is the other part in the screen that has a big impact on the battery. In a logic way, less the brightness more the battery life. (Greatest Savings)
Now the latest ROM's have a new amazing feature, we can change the interval the sensor works to achieve the ambient light, reduce the brightness minimum value (that's by defect way too high in low light conditions), and customize your prefered light levels (that are too way too high in default configuration).
By reducing the sample interval sensor a bit and reducing the minimum value a lot we can achieved abetter battery life in a great manner.
Also adjusting the light sensor levels to a more reliable one's that are by far lower than the default one's we'll achieved a more optimize system that consumes less battery.
Note: This are my actual, after 2 weeks of adjust, values but I'm still working on them, they are no 100% reliable.
CPU
The CPU is a great beast. In terms of battery is well adjusted, by as always, we can achieve a personal optimized system (this is Android, yeah!) that will balance performance and battery life. (Great Savings Underclock and Undervolt combo).
A very good speed and fluidness can be achieved with a very good optimized and well balanced performance-battery friendly system.. and yes, with the last advances in kernels and ROMs, we can have a perfectly smooth system with a top speed of 1000Mhz.
In the other hand Undervolt will help us to achieve a cooler system with some battery gain. With Undervolt we´ll limit the max. value of the Voltage for the specified frequency, if we have a kernel with Smartflex, this one we´ll allow lower voltages depending on the power need of the CPU.
Two important things:
1. It has been tested that the 700Mhz frequency is prefereable over the 300Mhz one, due to the drops on frequency signal of the phone.
2. Undervolt values are not the same for everyone, it can oscillate depending on the individual CPU. When I UV I always test my system with an Stability Test app.
Connections
GNex is a phone...also.. well, it's a super computer with phone capabilities. Due to the "always connected" philosophy the optimal baseband will save a lot of battery. An optimal Baseband and Radio (region optimized) will require less power and time to connect to the antennas and will have better connection always (less power irradiated). (Medium savings).
The Radio should be updated and region optimized, there's a magnificent post made by josteink that explains all the details concerning the Radios with links to every one available.(GSM)
[Radio] (GSM) Galaxy Nexus I9250 Baseband dumps collection & discussion
European Radio Recommended: XXKK6 (XXLA2 is giving too high "Phone Idle", resulting in drain problems)
For the CDMA version there is another magnificent post by ready5 with a compilation of every RADIO for the CDMA version of the GNex.
(CDMA) [RADIOS/HYBRIDS]*UPDATED* 4.0.4 FULL 2/6/2012 PLUS FRIED RADIO Halp!
In the GSM version on the other part the 3G, HSPDA consumes great great great battery juice. If you are not in WIFI and are not using the data connection, a great way to save battery life is changing from HSPDA or 3G to 2G networks (this is really noticeable if you travel a lot by car or train, cause you are continuing connecting a reconnecting from different radio antennas).
There's some ROMs as Liquidsmooth that allows when you are not on WIFI and after an specified delay, to change to 2G automatically (or low consuming) networks when you have the screen off. This is a great way to save battery when you are not at home, reducing the standby drain of the phone outdoors.
.
The automatic 2G when sleep is a main function of Juice defender. Thanks to a1exus for recommendation.
In the CDMA version the LTE consumes also great great great battery juice. If you are not in WIFI and are not using the data connection, a great way to save battery life is changing from LTE to 4G networks (this is really noticeable if you travel a lot by car or train, cause you are continuing connecting a reconnecting from different radio antennas).
Thanks to thenickisme for this!
WIFI
Wifi has a crazy history on the GNex. After talking and talking, posting and posting, it has been tested that WIFI always on while sleep is the best way to achieve a longer battery life. (Medium savings).
Also the new ROM's have amazing feature that change the WIFI interval (we normally stay at the same WIFI always), increasing the value will save batterty life reducing the continues scans that produce the WIFI Always ON requirement.
Services and Apps
The best thing of Android is that we can configure anything, one of the best and underestimated feature is the Freeze or Service Uninstall. We did it before in Windows and we can do it now. Through the Apps section in Preferences or the mythic Titanium Backup we can disable or uninstall an internal function of the systems that is normally used, giving more resources to the system and in some cases, saving some battery. (Low to Minimum Savings).
There are some ICS functions that no everyone uses. For example, I don't use any Bluetooth, NFC, Google Voice, Google Search or Speech function of the system, freezing or uninstalling them will optimize our system giving some battery juice.
Note: This is a dangerous thing if you don't understand what you're doing. Make always a Nandroid before Freezing or Uninstalling an essential function, just to be cautious.
According to the Apps we have to take in account the Background Syncing or Sync Interval, most of the time the apps don't need to be synced every 5 minutes, like weather, if we make longer updates we'll achieve a good saving battery related. (Great Savings if many apps with many connections).
Widgets, 5 homescreens full of widgets updating in real time could be detrimental to the battery live, take care when adding widgets and as said in the previous paragraph, change every widget preferences to update in longer times than usually they have by default. (Great Savings if many apps with many connections).
Bad Apps are the one's that not allow our device to deep sleep or wake up continuously our GNex. There are several on the market, Readability for example is a new one that wake up continuously our device attempting to download new articles, on the other part, some time ago Widgetlocker had some problems not letting deep sleep the GNexus (don't know now). (Great Savings if there is an apps giving deep sleep or wake ups problems).
Pointing on this, the best way to know if any app is not behaving well in the system is through 2 apps:
- BetterBatteryStats, that will look for any wake up of the device while sleep.
- CPU Spy, that will tell us if the device is deep sleeping ok or not.
Other things
There are other things that will help us in a great or minor manner to save battery life.
Sync Data usage (Google services like contacts, bookmarks, etc..) consumes battery, if you limit this usage, you´ll gain some juice. The new ROM's in the Powersaver tag will allow you to limit this sync usage. (Low Savings).
The Dial Pad Touch Tones and Vibration affects battery also (yepp it's true, and in a great way!), disabling this features will give you some extra battery juice. (Low to Medium Savings with combo sound plus vibration).
The Google Location services and Backup&Reset Data consumes great battery also, limiting this services will gave you some extra juice. (Medium Savings).
The last little thing that will help you save batt life will be the Automatic Date&Time option, disabling it will give you some extra juice also. (Lowest Savings, practical minimum).
Live Wallpapers, they are very nice but will drain your battery quickly. Static Wallpapers are preferred, and if posible, dark ones. (Medium to Great Savings).
Experimental
This are new tweaks that normally appear in new/advanced kernels, his use according to battery save is still not really tested or can have a detrimental on the physical conditions of the device/battery. Use them with caution or if you really know what you are doing.
[MOD][KERNEL]Battery Life eXtender (BLX), this is a tweak created by the popular Ezekeel and in his owns words: "Older types of rechargable batteries exhibited a 'memory effect' which made it neccessary to completely charge/discharge the battery when using to prevent degradation of the capacity. Modern Lithium-Ion batteries like in the Nexus S do not show this problem and thus it is not necessary to use the battery in complete (dis)charge cycles. In fact on the contrary, it is commonly accepted that both very low and very high charge states accelerate the degradation of the battery capacity (that is why you should store Li-Ion batteries at around 40% charge).
While a low charge state can be simply avoided by charging the device more often, the battery in the Nexus S by default is charged to around 95% capacity and I could not find any app or tweak to stop the charging at a lower capacity. Thus the only way was to use the manual override and pull the cable which is annoying since one had to monitor the charge state." (Unknown Savings).
Galaxy Nexus is charged by default to the 96% of this capacity, with this new tweak you can gain this 4% (don't know for sure if you can get the 101%) of battery life, in 4 hours screen time, more or less 10 minutes, but it can be detrimental on the long way to the battery physical life.
You can found this tweak in the last nightly of Franco's Kernel, and can be activated via his own app.
You can find more information in Ezekeel post here at XDA.
[MOD][KERNEL]Undervolt of IVA and CORE Voltage, new patches let undervolt the IVA (hardware media decoder) and CORE (GPU Voltage), I'vce been playing with this all the day and I've managed to undervolt a 15-20% de original frequencies. (Unknown Savings).
I understand that with this we are limiting the maximum voltage they can use, letting them to use lower ones according to GPU load. I'm not sure at this (GPU uses smartflex also ¿?) but with a descent of 20% on the voltage could result in longer battery life while playing games or seeing movies.
I'll try further undervolts, but this are my actuals on a stable system.
You can play with this voltages via the last nightly of Franco's Kernel, and via his own app.
Take care playing with this, could result in system instabilities, reboots, freezes, etc.
Links of interest
- BetterBatteryStats, A high battery drain is often a limiting factor for a great user experience.
With BetterBatteryStats you can analyse the behavior of your phone, find applications causing the phone to drain battery while it is supposed to be asleep and measure the effect of corrective action.
- CPU Spy, This is a simple app to display the time the CPU spends in each frequency state. This can be a useful tool in diagnosing battery problems or tweaking your over-clock settings.
It also displays the current kernel information.
- StabilityTest, StabilityTest is a stress-testing tool for android devices with error reporting.
StabilityTest is a CPU, GPU, RAM/memory stress-testing tool for your device, whether stock and unrooted (limited functionality) or rooted and overclocked with SetCPU, SetVsel or similar tools.
Extended Battery
At the end, the best way to extend the battery life is with an Extended Battery, they are not very expensive and only increase a little bit the thickness of the device. They can be bought at several places through the typical places as Ebay, Expansys or Amazon.
Important: Take in account that the CDMA and GSM versions have different batteries and they are not compatible, normally the GSM one is longer and black and the CDMA is wider and blue.
Borrowed from Buddy Revell
Calibration
Once a month we´ll have to calibrate our battery so that the information to be shown on screen is accurate and true. The steps are as follows.
1. Charge the Nexus until the indicator shows us is 100%.
2. Disconnect it and let it discharge until it turns off by herself.
3. Then load up fully charged. Note that this state is reached after one hour approx. since it shows that is already loaded.
Note: There are several apps in the Market that help calibrate the battery, although I have heard that in ICS Google has changed the file location does. Log of our battery so many of them may not work well if they are not updated.
great post especially for a new gnex user. will look through these options thoroughly.
Very nice. Thank you! Took a few suggestions.
Looks like I've got some work to do =D

What rom is that? You should state that ...
Awesome. Those custom backlight levels are going to save a good amount of battery. I tried using a filter, but it made using the phone in sunlight impossible.
It's working inside well and based on what I see from the custom levels, it should have no issues once I take it outside.
As for the underclocking, comparing iOS and Android isn't fair. iOS has an advantage with its closed ecosystem. I personally overclock the GNex to achieve the same snappiness I had on my iPhone 4S. Sure the underclocking will save battery, but I might as well be using an older phone if I'm going to underclock.
When it comes down to it, everyone's battery is >50% screen consumption. Your custom levels are going to tremendously increase battery life.

With the iPhone comparison I just tried to emphasize that sometimes underclocking results in the same snappiest system, but yes, is a little unfair though (but I can assure that with the latest Kernels and ROMs that have been released, I have a totally fast and smooth system with only 1000Mhz).
Well done good job
Good guide. Rather than seeing multiple thread's about awful battery life its nice to see people talk about how to maximize their battery life

Good guide—thanks for taking the time to make it—but along with it’s very good parts, it has quite a few inaccuracies, is misleading in some places, doesn’t fully explain the ramification of making many of the changes that are proposed and makes questionable changes for very little gain. Amongst other things, my major issues with it are:
You wrongly assume a device that does not get four hours of screen time is not optimized—this would be incorrect as one can get four hours of screen time with the stock ROM and default configuration.
The stock ROM does not allow you to customize the backlight and CPU—so you should point this out.
It’s condescending to the iPhone (while the GN might be better in many ways, patronizing another device has no place in a “guide”).

Thanks, but the guide tried to be a compilation of many procedures that would give you a longer batt life. Some of the recommendations give you maybe 4-5% more autonomy, some of them 0,5%, don't know because I'm not an engineer and don't have the tools and time to measure the actual rate of discharge of the device, I'm only a user that took some time in share his personal experience in the last 4 and a half months with the device.
1. It was a way of talking, did not tried to assume anything because was not thinking in anithing out of the people that are not having more that 3 hours batt time, was a simple way of selling something (a well/bad introduction depending on the eyes or mentality of the reader)
2. We are at XDA and this is a developer device, I asume a minimal technological base, I was assuming this. But I point this out because I also think that will help some people.
3. Tried to emphasize that while the over sold as an ultra-quick device is only 1Ghz Dual-Core, the GNex can be as fast and reliable as the iPhone 4S with the same speed, and also saving batt (and in addition you have 450 more Megaherzs if you want to use them.. if you root). It’s not condescending cause if I would have liked to buy an iPhone I would bought one as the 99% of the people here.
I am a simple user, as everyone here, trying to help people as people has helped me developing great ROMs and Kernels I like positive and concrete recommendations over vague and negative ones.

The Calibration section is a little confusing. It only takes 1 hour to go from 0% to 100%?
Also, do you know anything about calibration with ROMs that only allow you to charge to 99%?

No, it takes 1 hour after the GNex indicates is fully charged. I'll try to change it in order to clarify.
No, sorry, maybe you can "delete battery logs" via recovery. (I never did it, and don't know if can be detrimental).
I have been searching as to what is the proper way to cycle charge so I can get the best battery life after installing new kernel and ROM.
However I seem to find different answers
One to drain in completely others say don't?
What do I do?
Unless someone links you to a peer reviewed research paper, you will be reading random anecdotes.

I wouldn't consider the manufacturer's suggested charging cycles to be "random anecdotes" even if they're not published in a peer reviewed journal.
"Completely draining" should not be practiced on a regular basis with lithium ion. You can't (or shouldn't be able to) reach an actual complete drain before the phone shuts down. If you could (or ever do) the battery would become useless to you as there is a point of low discharge where lithium ions can no longer be charged by a standard charger.
And while most of the time the shut down of the phone and the subsequent charger connection happens before this point - there have been plenty of people who have let their phones go till they shut down then go to charge their battery only to find it will no longer charge.
So every time there is a drain of your battery to the point your phone shuts off you get real close to that point where you will no longer be able to charge that battery (unless your one of those techno chemist electrical engineer types with all the appropriate tools and materials handy).

And i know i've read somewhere about someone suggesting that people go through this arduous process of draining the battery to a point, charging it fully, draining it completely, and charging it fully again (or something crazy like that... i don't remember exactly) to make the phone detect the full capacity of the battery and avoid any "memory effect", and i believe that whole idea was even shot down by someone at Google who works on the Android OS as being a complete crock.
I really don't think there is any PROCESS that can be done to give you the optimal battery life, aside from what can be done to prevent apps from draining the battery constantly. Some people recommend having a fully charged battery, or having the phone plugged in when you wipe the phone and install a new ROM... i've rarely done that. I've even wiped and installed roms at like 40% battery life... sometimes a bit lower. But in my experience, battery life has more to do with the ROM being used than what you did to try to MAKE the battery life better.
Running a touchwiz-modded ROM like DrewGaren's Serenity and stuff, i'd generally be lucky to get a full day of battery life seemingly no matter how much or how little i used the phone. I'm not what i'd consider a heavy user.... haven't really used my phone much all day today, though it did spend a good portion of the day on the charger. But i'm running the latest build of Task & Ktoonsez AOKP ROM, and it's been on battery for 9.75 hours and is still at 85%... but that's only with 20 minutes of screen time.
Anyway.... all i can say is from my own personal experience, but i don't think there is really any definitive process one can follow to improve battery life beyond what the software itself will do anyway.
Whether or not it has any effect on actual battery performance i would say that running a 'full' cycle or two of drain and charge for android to learn the battery capacity. Probably doesn't have much affect on a stock battery but when i purchased my 4400mah battery it took a few cycles to get an accurate reading from the charge meter. It would drain down to the warning in what it was expecting the stock 2100mah to be dying and ran FF3 for atleast 2 hours non stop on 1-5% until the battery actually gave out. On top of that it couln't decided how much it really wanted to say was remaining, it would jump up and down a percent or two, obviously confused of what to do. Whether or not its necessary to run it to this point is debatable, but with android or myself not knowing how much charge was actually left in the battery i did.

Hello,
I know, I know, there are many threads on the battery issue. But I'm struggling just too hard with this. I've researched and read every thread on xda and other forums elsewhere to glean as many tips as possible which has certainly helped, but something just doesn't seem right.
Currently I'm using a battery saver app - Easy Battery - which does help considerably during idling and off-use periods - the DINC at least has some charge left to make a few calls and check voicemail when I'm finished on the job site and going home, but when actually using the device it seems like I can just watch the battery drain down - it's really disheartening.
My device details are below. I'm using the best performing kernel I've found after much trial and research. I've deleted about 10 - 14 resident system apps to improve performance - the DINC is as bareboned as it can get. Maybe I can delete a few others still.
I understand JB is more of a battery drain, but can it be this bad? After a full night's charge, I wake up and check my mail in bed, some quick online news browsing, looked at one or two video clips, 5-10 minutes each. I spent about 20 minutes on the phone. Looking at my screenshot, the battery's drained 40%, IN 37 MINUTES!!!
Also, some hours of the day the battery life seems better...? Sometimes I can perform general tasks on the phone, watch a few video clips, do some reading for an hour straight sitting over a pint and there seems to be comparatively little drain at all, certainly not 40% worth of battery drain in a half hour. I just don't get it.
Am I need of a new battery? Is there a super battery for the DINC? Should I be limiting the number of 'recent apps' in the Recent Apps switcher? Is there another Performance setting I'm overlooking? I/O scheduler setting?
Please, please, what can I do - any additional tips would be greatly appreciated. I love the DINC. For me, it's the perfect sized phone that I like, outside of any device functionality at all. Maybe I'm moving on though. Ugh.

if you have the original Dinc 1400 mah battery, maybe your battery just doesn;t hold a charge anymore.
what I do is I don;t even charge my batteries in the phone really. i find that when I charge the battery in the phone, the battery drains quicker. I bought an universal external charger and rotate a couple of 3500 mah batteries after running them down completely. I carry a spare with me if I need but usually my phone lasts into the next day.
you can get 3500 mah batteries for about 5$ or so on eBay(last I checked). the universal charger goes for 9.99 on NewEgg or Amazon. good investment
What I've done on CM10 to try to extend battery life:
Keep my screen locked at 25% brightness but can toggle into 100% or auto when necessary. On CM9 (before I was crack-flashing CM10) I played with auto-brightness levels that were discussed in this thread and they did help. 'Auto' is normally too bright for me, anyways.
Turned off background location reporting in Maps. This will neuter some things in Google Now, tho. You can see how often your phone "checks in" here.
I used SmartAssV2 on CM9 but went to interactive on CM10. No quantitative data that it helped battery life, but it passed my eyeball test after a week+ on both. My phone is flaky on under/overclock so I keep it at 245/998.
I leave 3G on, WIFI on, GPS off, BT off 99% of the time.
Hmm, great suggestions. An external charger(though I'd prefer not to be regularly opening the casing, I'll look into it); 3G radio off; locking brightness at 25%, toggling when necessary; background reporting off. I'll also keep experimenting with a governor and try a week on interactive. A really great kernels guide: http://forum.xda-developers.com/showthread.php?t=1369817.
I have a spare original battery so I've got that in and giving it a powered-off charge. See how that does on top of other adjustments.
BTW Both batteries I own are model BTR6300B 3.7VDC -- 1300mAh 4.81Whr - tekweezle mentioned a 1400mAh battery and other available batteries that are at 3500 mAh now - I guess I'm looking into new batteries as well -
cheers for the responses -
I recommend just getting a new battery on ebay for 5$. Also get juicedefender it doubles my battery life. Also try tiny/pons cm10 rom that has great battery life.
Definitely getting a new battery; I'm already using tiny's rom which continues Pons' CM10 rom builds. Really great -
cheers
Obviously, if you are using your phone non stop, you'd be lucky to get 6-8 hrs of usage. But the true indicator of what a phone does is how often you don't have to be attached to a wall outlet or hunting for one.
I don't know if others get similar results as me but this is more or less typical of me with light to moderate usage-checking email, Facebook, some Web browsing, occasional phone call or text message plus leaving my phone on overnight in stand by.
By the way, how I am on pons/tiny 12-9-12 and working well.

btw, this is the external battery charger I am using. awesome thing is that it charges at 600 mah so my 3500 mah batteries charge up in 4-5 hrs or so. since it has moving pins, you will be able to use this to charge any flat battery for any cell phone or camera you might buy in the future.
the SEIDO HTC EVO modified one I got on ebay charges at 500 mah and for some reason it takes 8-11 hours to charge a battery and I am finding out now that it doesn;t even charge them completely even when it thinks they are completely charged. i take a battery that is charged in this and put it in my other charger and still needs charging of about 10 percent!

I get something similar, probably a little worse, in send/recv about 50-100 texts a day and checking 2 gmail and 1 exchange account constantly. My battery does tank when I'm actively using the phone and really all I can do there is manage the brightness of the screen. I've been doing my tweaking to try to increase battery life when I'm not using the phone. In 7 hours last night it only went down 3%. When I first started using JB it was 10-12% a night.
Great, great info - love these forums, and I love android!
tekweezle - could you tell me exactly which 3500 mah battery you're using with your DINC? Also - no issues whatsoever with the pons/tiny 12-9-12? I thought I saw a few things reported with the 11-28-12 and stayed away from it, staying with the 11-25-12.
cheers!
i have an expensive SEIDO battery that I bought from Amazon in the beginning for about 59$. Never thought the capacity was all that great till i found out that my battery wasn;t even being charged completely. not really worth the money but at the time, it was all that was available

The others, i just bought generic flavor of the day batteries off of eBay for 5$ each. basically throw away items. just search for HTC 3500 mah Incredible battery and you should get some hits.

Hello Champs.. I am first time user to this forum so pls excuse any idiot questions if it may seem.
I tried to go through threads to find answers but got completely confused, so though to put my question in simple words here.
I have Desire HD running task killer and Juice defender ultimate with extreme power saving option set and also optimized settings but still my phone don't last more than a day of normal usage. I just check emails, read news and call.. I do not play games and use any CPU intensive app. Phone is not rooted and running 2.3.5v of android
One of my friends told me after flashing ROM, battery power is improved by 40% in case of his tablet, so I am wondering if there is any suggestion for me to use for my Desire HD mobile. I have tried all options at application and settings level to improve the battery life.
As I am not too techincal in this field, if someone could write me few high level steps from start to end to get better battery life ROM and / or jellybean on Desire HD, I'll try to find out low level details of those steps in this forum and root (and flash) my mobile.
My sole requirement is to get as much battery as possible and if possible, some latest android version (4.1 or 4.2) to avail the new features.
Also, would there be an option to take the snapshot of current mobile setup in case if rooting / flashing goes wrong, I could revert back to the current version without loosing settings / data.
Thanks for your help.
two things, go to settings>about phone> battery
Or something like that. Take screenshots of your battery consumption, and the amount of time for each. Without that we can't know what's really causing your battery drain.
That said, a day of use will pretty much wind down your phone, the DHD has a very poor battery, decent sized screen, and most modern smartphones don't last terribly long anyways. However, you said you weren't using it too hard, so I'm not sure what it could be
As for juice defender, make sure that the intervals are set to no less than 15 minutes. 10 minutes pushing it. if you set it to 5 minutes, your phone will constantly be waking up from sleep (ultra battery saving mode), and constantly enabling and re-enabling radio. That'll cause more drain than it will save. At 15 you'll notice definitive increases, and at greater your battery will only get better.
Get rid of the task killer, or disable autotask killer and keep task killing to an absolute minimum. Never kill all your user apps at once. Kill only very large resource hogs (e.g. after playing a game, kill it). An autotask killer is very bad for your phone, and for your battery. Linux naturally tries to keep as many processes 'running' or cached in the background, using up a lot of your ram- it makes multitasking better, so in linux this is a good thing. With windows, it does the opposite, and if you run out of RAM you're screwed. A task killer will try to ruin that behavior, and in the end both performance and battery life will suck. It hurts battery life because after you kill that app, it'll just restart itself in the background- using more CPU therefore battery. Plus it also wakes your phone up from sleep when it needs it. I would only recommend a task killer for a phone with 512mb of RAM.
If it's an older battery, you could also have lost a lot of it's charge. I recommend installing battery monitor widget, and letting it run in the background. It'll estimate your mAH (battery capacity). If it's over 1,000, you're fine. If it's around 800, not bad, still doable. If it's at around 600, I would recommend going in for a replacement battery. I'm using an Anker 1500 (amazon), and I highly recommend it. Mugen 1600 is very good one, but it'll cost you a lot more money. I would not recommend an original HTC one.
finally, installing a custom ROM may or may not help battery life. With HTC Sense based ROMs, I've noticed a battery increase. In AOSP (unmodded, as google intended) gingerbread ROMs, you'll also notice a battery increase. With AOSP ICS, JB4.1.2 and 4.2.1 battery life is hit and miss, some ROMs will get you better battery, some will get you worse. You'll need to experiment around with it.
Also, yes you can backup everything after you install a custom recovery. I recommend looking up AAHK (advanced ace hack kit) on google and youtube, as well as rooting and S-OFF in general on youtube.
Thanks for your reply... Really appreciated. I'll look at the suggestions and see if it is unnecessary to root if 1 day battery is expected.
Do you think recommended high power battery actually improves usage time or people just compare their used up battery with new high capacity ones and think they hv got more juice in it. If high capacity ones really give another 2-3 hours of browsing as compared to OEM 1230 mah battery, I would rather buy it instead of flashing Rom.

The Battery Drain Very fast Is This Normal ?
I'm on Official 12.0.8 Global
This forum feels dead before it even came to life. Im no android pro by any means. I don't have any such issue but, please provide more details. When did it happen? After first boot? How long does it last? Have you checked in battery statistics to check which apps drain battery the most? What are they? And also your miui version
debloat thats the only thing you can do for now
Just writing that the battery is somewhat draining fast, leaves very open why this could be or whether it is just interpretation.
For me battery feels extremely well on miui 12.0.4.0 RKQEUXM.
Such that I can use the phone for two days straight under light usage and charge somewhen on the third day.
Provide better info, like screenshots of the battery graph and app list where you see which app drained which percentage of the total.
Or use apps that analyze further, like better battery stats or such.
You can also compare usage to other phones with comparable battery capacity, etc.
This could give a clue.
But other than that, such statements are rather irritating and the best suggestions are just, provide more info or do something general like, yes, debloating.
Turn off miui optimizations in developer options.its effect on your battery drain.i try it for my self
